My problem is not complicated. I want to remove 2FA because I lost my phone. Only way to remove it is to send an email to support (that's quite stupid by the way).
I have sent them a signed message of an address I used in the past. It should be enough to prove I'm not a scammer

PS : Still waiting ;-)
I'm still waiting. It's been 10 days.
I hesitate to post here every day until they answer my support request...
. No answer, excepted from Micro who is very nice but can't do anything.
