There is apparently a way to set up a bridge that will allow you to access it, but that sounds like an awful lot of work. It also requires connecting to a PC running the software, and I would imagine it affects the security of the messaging (which may be the reason to choose proton mail in the first place).
I'm in the same boat - with them for the encrypted email, but it does hold me back from using third party apps on mobile. Hopefully they get an easier way to use third party apps on mobile. Will probably just end up being a mobile bridge app or something
Edit: just tried this and it didn't work. Proton bridge only listens on 127.0.0.1 and doesn't accept incoming connections due to security concerns.
If I were in your position, which I am and will probably end up doing this, is vpn into your home network and just connect to the local IP of your bridge server.
WG tunnel on F droid allows for you to auto connect to your wireguard server when you leave your home net, and auto disconnects when you get back on your home net.
Personally, I'm unsure if proton bridge listens for external request or if it only accepts requests from localhost? If that's the case it may be an issue.
No IMAP/SMTP support with ProtonMail. You have to run their bridge application locally to get that functionality.
IMAP/SMTP does make their encryption at rest impossible, AFAIK similar providers like tuta don't have those either.
Yes. Calendar is even worse. There's no bridge at all. Proton should've used a standard protocol and put their encryption on top of it in a separate layer to make it comlatible with other software

That's a hacky approach ngl. Security would've left the chat the exact moment they had a thought about doing that in their heads. Proton is a known company. Imo developing their own protocol is a good decision if they can't make the existing one work properly at all.
