Same with Android, only one account in free version. But I think when switched to pro, one can use more than 1 proton mail account in their app.

My understanding is that this isn't a free/pro distinction, but a "Feature on the Roadmap". But I'd be delighted to find out I'm wrong.

I stand corrected[1], premium users can 'Combine multiple accounts into 1 account'.

Yep, that's fine, but it's not much of a firewall. And unless I'm mis-reading this, this doesn't allow you to combine multiple domains.

I've setup multiple domains on the same Protonmail account. You can create new addresses (@protonmail.ch/protonmail.com/pm.me/domain) with a paid account (iirc up to 5 total addresses with Protonmail Plus).
