Proton mail user experience nightmare

They later allowed people to register under proton.me, which is shorter

Sounds great, but why didn't they register protonmail.me when registering proton.me? Think of how many people accidently registered using protonmail.me, which goes nowhere.

So annoying . Some websites do not allow you to change the email until after verifying it, so you are locked out for good if you make that mistake.
