I was very excited to learn that Folders were in development due to Vaults being locked for Proton Pass paid plans. It is extremely disappointing that Folders are also locked behind a paywall. I already pay for Mail Plus, and it is not financially feasible nor practical to pay nearly double for Pass for only one feature. It should have been announced from the beginning that Folders were going to be paywalled. Please consider making at least 5 or 10 Folders for free (unlike the the 2 free Vaults which is pretty much useless when the Home counts as one).
