This was kind of my experience too. I didn’t really use it for too much and everything about it was slow and felt icky, so I just haven’t bothered with it since. I think the only thing I really used it for was Nextcloud News for RSS, but I’ve since switched to FreshRSS, which I’m happier with. Actually, that’s not true… I used the WebDAV stuff to sync papers with iOS from git annex for annotation, and I kind of miss that, but not enough to set everything up again. It just felt heavy.
