Same for me. Smart audiobook was great on one device, audiobookshelf even better since being into selfhosting.

To answer directly, MAM is a great private tracker for many reasons, including their epub library. Bibliotik is supposed to be good but harder to get in.

For other options, have a look here.

It was a bit rough in the beginning I admit. I’d recommend giving it another try.

You can look up this thread that has an updated tutorial.

Very easy to follow and should get you going.

Are you thinking of Vanced? Revanced has been steady ever since I switched almost a year ago.

I usually use slavart, but it’s been unstable lately. With it, you can download anything from Deezer and qobuz.

In Smarttube, go into settings and link device or something similar (edit: remote control). On your phone, go into settings and link TV and input the code Smarttube will give you.

It acts more as a remote, you need to have Smarttube already opened. It’s not perfect, it’s a decent compromise.

Soulseek (nicotine+) and Slavart on divolt (FLAC files from Deezer and Qobuz).
