Not op. But I had plex server and torrent on raspberry pi. And it would become slow sometimes.

Initially it also only partially worked for me (couldnt login) bcz i had a mistake in authentication url. Later i followed the guide precisely step by step and it worked.

Cant really say anything about this. I have 1.23.3. It worked on this version for me. I dont know if its the latest one or one of the older versions

Works again after revanced patch.
