Their official phone app was, and still is, garbage. So I used a 3rd party app.
When Reddit killed API access, they did it in such a way that it killed that entire ecosystem abruptly. I'd have happily paid a small fee for API access to continue using the site, but no such option existed. Even at this point I'd still do it but that option still isn't there in a way that's useful.
After that, I found out that the 3rd party app i liked the most, Sync (on Android), had a Lemmy version. So I downloaded it to try it out. And here I am.
