I’d love to add by proton account (the bridge works), but currently I don’t see an option to set it up in Geary. On second step of the setup I keep bouncing back and I don’t see a way to set hostname/port (in case of using the bridge that would be localhost) for imap and smtp.
edit: nvm - it seems it was a glitch with bridge. I tried a couple of times and finally it worked.
