It took about 2 days of using nextcloud files across devices to experience unreliable syncing from Nextcloud on Android.

I installed folder sync pro on android and that has helped a lot, but it still irks me to use 2 tools when 1 should do the job.

It’s fairly clunky. The developer is a nice guy and responds really quickly, but files sometimes didn’t sync and I got an error twice where it just completely stopped syncing.

There also isn’t a proper setup guide or documentation (but you can always add the help flag halfway through your jar usage to know what parameters you’re missing). The developer has been kind enough to help me through that though.

It might just be a skill issue on my end of course. Though needless to say I moved back to something else after a couple of months (In my case to Seafile)

Also its Dutch translation is acceptable (I did that)
