After a month of testing Proton between my wife and me, a couple things happened that made me feel glad we didn't move our emails right away. Back to square one. Our accounts were suddenly blocked and a premium was asked to unlock them. The reason is that we had created multiple accounts. I explained that each account is used for email accounts we have and use for work and life (basically 2/3 each with different recovery emails that come from our existing ones)... No reply from support. 👋
