Joplin on IOS won’t sync, presumably because I’ve updated to version 150/151 on Windows. Error type 13. I hope when a new IOS version is released it will work again as normal.
I feel such problems, where mobile Joplin can’t sync with the desktop version for an unknown time, could put people off using it. It might be worth noting for the future to warn users not to update to a new desktop version until the corresponding mobile versions are available.
