Issues with /e/ OS: 1Password app where I should use QR code for activation failed, needed to do it manually. Another app could manage QR code.
Secondly, heard from another person that for the Swedish BankID app activation he needed to use NFC, which did not work in that app (luckily I did not need to do that step for my activation).
I think both these issues might be related to the fact that the microG services that tries to mimic Google services cannot mimic to 100%.
