Agreed, I always leave everything seeding and also disable queuing. Leaving "Global maximum number of connections" at default setting (can be set lower) along with configuring Global Rate Limits Upload/Download to something appropriate works perfectly.
Torrent clients are smart enough to juggle the active torrents and share the allowed bandwidth between them without you having to micro-manage the whole thing.
Was going to comment the same, this issue has existed for some time for other apps. LibreTorrent ran into the same issue and now the F-Droid version is their full-featured app while the Google Play version is restricted due to Google.
Interesting that Nextcloud managed to last this long on Google Play without running into the same limitations (until now that is).
