Many thanks @madalenamonteiro and Thomas @tkrunning. This still leaves a group of investors who had applied in 2021, and completed biometrics in the first half of 2023 (when biometrics schedules were opened), and did not sue.
See this post: Awaiting Final Approval (Stage 4) - #2153 by servettasman. The AIMA email does not say what happens with these investors, or how they are /will be processed.
The only statement referring to this group in the AIMA note is: "Caso o pedido de concessão de ARI já tenha sido formalizado, deverá desconsiderar a presente notificação. Vague at best.
Any insights?
