If Gmail is rejecting your custom domain, you haven’t setup your SPF, or DKIM records etc for you custom domain that authorizes proton to be a valid email sender.
E.g when Gmai receives an email from a custom domain it will look up records to confirm the mail server sending it is valid.
Checkout https://proton.me/support/anti-spoofing-custom-domain or search proton SPF DKIM for guides.
You wouldnt have issues sending from a proton domain as they already have these in place for you.
I think the dev got really enthused when the twitter exodus came to fedi, but then it left and wasn’t the next big thing. Plus maintaining or building an app turned out ultimately what they wanted to do. First it had a public ui, then got scaled back to a server if I recall.
A few more apps than I was aware of so quite encouraging. Personally waiting on affinity to make the jump. Fingers not xd
LocalSend on both devices is something I’ve used
Getting anxious just thinking about it.
Might sound weird but it was the PSP I imported at launch.

I use Navidrome + audinaut as my android app (I only just checked to find out that development on audinaut stopped 4 YEARS ago), so will be looking at this thread for new suggestions…
