Sync problem on android nextcloud app - it was very slow, showed zig-zag pattern on bandwidth usage. That bug was solved but nextcloud app still does not utilize all of bandwidth. Can not fail and resume, basically there can be months of pictures lost since it resumes, crashes dies, does not resume next time. The android app that is. Disclaimer: I fixed some of these bugs, so seeing the source-code was repulsive enough, but there just isnt anything else better as far as I know.
