Hello, My synchronization has not worked for a few days now and I get the same error code 909992 on all devices (Win10, IPhone). I have installed the current client from the store on all devices. Nextcloud version is the 16.0.2. What I've already tried is to deactivate the synchronization and synchronize again. Delete the data on the cloud server, new initial synchronization works. But no updates on this I always get the error code 909992. Can someone help me solve this problem? Thank you lars
