Lisbon has had much, much worse days than this (4 hours I think once?), long before EES was turned on 
This statement comes after the PSP (Public Security Police) on Tuesday described a “critical day” at Lisbon Airport, with non-EU passengers waiting more than 90 minutes at departures and arrivals due to the new electronic control system.
I entered Berlin last night. I do have reciprocal “Global Entry” privileges for Germany. In the past, I used the EU scanners and had to talk to an agent and get a stamp. Last night, the gates opened, I walked over to the agent, and he waived me through. Hard to say if it was because of the reciprocal “Global Entry” or because of my ARI visa. But I don’t have an entry stamp in my passport.
wait… what is that reciprocal Global Entry and how do we get it?? 
is it just automatic for any U.S. Global Entry holder?
My spouse showed a valid Portugal residency card and US Passport in Frankfurt on October 16, traveling from Porto to SFO. The Border Control agent said he could use the eGates (for EU Citizens) next time, and should get the German EasyPass if we were going to go through Germany often. (I think that is their version of Global Entry)
Pretty sure I’ve read numerous reports that German ports of entry were not stamping passports for holders of Portuguese resident cards already. I know that the border agents at LIS are confused about this because I’ve had both conversations at different times with them (one where they insisted they must stamp my passport and another where he was bemused that I insisted he did so). Indeed, after the e-gates I’ve missed the stamping agent on occasion when I’ve arrived and nobody cares when I leave. I believe that Germany had already worked out what an operational nonsense it was for holders of EU residence permits so I don’t think it’s surprising or indicative of any change there if they didn’t want to stamp you this time.
Correct. I enter / leave schengen through Germany often now, no stamps
EasyPass is the German equivalent of global entry. The US allows German citizens to do GE, so Germany reciprocally provides EasyPass for Americans. You can do it at any of the main airports if you stop into the police office. No cost, and just have to fill out a simple one-page form. I got through the process in about 10 minutes and it was working fine a couple hours later.
Once you have it, you can use the egates even without a residency permit.
This is a known thing. There has for many years been general confusion amongst border guards across the EU as to whether to stamp or not - whether or not they are supposed to, they often don’t. I have had Swiss guards also just wave me through over the years without a stamp. This has even been noted by the EU authorities with a memo, wherein they also expressed an understanding of the challenges involved in figuring out whether an EU resident has overstayed schengen in some other EU country and more or less promulgated a “benefit of the doubt” rule of thumb. I posted a link to that document here years ago somewhere.
fwiw, arrived Funchal (Madeira) early this afternoon… rows of EES biometric machines still wrapped in plastic, as they have been for well over a year.
Which is a bit odd. Often companies/orgs. like to “experiment” in Madeira because we’re reasonably modern, but there’s not too many of us if it all blows up 
Seems your mileage may vary!
UK Daily Mail still thinks Brexit was a good idea ( 
), so there’s a bit of whine with the cheese here…
What city/country did you enter Schengen?
So, flew out of Berlin today. Used the e-gates. Directed me to an officer, like in the past using EasyPass and the elates. He looked through my passport, confused there was no entry stamp. Asked me when I arrived, I said “last Wednesday and your folks waived me through”. He looked again, asked me if I had a German residency per,it (I used to, but never tied to current passport). He looked for an entry stamp a third time…eventually shook his head and waived me past.
Yeah, EasyPass or something. You have to fill out some paperwork, but it’s free
Here is a cross-reference to EU regulations regarding the border stamp control for a GV holder (ie holder of a residence permit from an EU country) commonly referred to as the 90/180 day rule :
Those quotes keep referring to ETIAS - if we’re talking passport stamping (or no longer stamping!) do they actually mean EES?
No, I wrote that about ETIAS. We’re talking about EES here, but the principle of it’s the same. Just really no digging is required for EES because it’s flat out stated. At the time, with respect to ETIAS, it really wasn’t clear - I posted that some three years ago.
It’s amazing how much energy I had back then for this kind of research. I’m not sure if it’s the rest of my life that sapped away my energy for it, or simple overload and exhaustion of trying to cope with the Portugal Experience. 
I truly, truly feel exactly the same way. Looking back and wondering where it all went.
Quick update: flew into LIS on 10/23. Went through the US electronic gates. I think that they reverted to the old process because it was the same double-gate machines that scanned passports and then took picture for agent verification. Went through, got stamped. No biometrics. No need to show residency card.
Same reported to me by my visitors on 20th. System is implemented part-time at best
