iOS app does not sync changes

I’ve tried restarting the app, moving files to another folder, renaming files, changing files. No matter what I do, my changes do not sync with the iOS clients.

The only thing I have found that will make it sync is to clear-cache. Once I do that, it syncs perfectly. But I have to do that every time a file changes.

iOS app version 2.16 (00012).

Just to rule out any funny business, have you removed and reinstalled the app?

I just reinstalled the app and tested twice, it seems to be working.
I will keep an eye on it, thanks.
