Upon upgrading Syncthing Android to version 1.5.0, I see the following in the browser UI of my Windows computer (also running Syncthing 1.5.0; and my Linux laptops cannot sync the affected Android folder either).

These messages are unintelligible to the layperson and such a person has little idea what to do to solve the problem. Here are things I have tried myself to no avail.
I have restarted Syncthing, on both the Android device and the other devices.
Ideleted (from all or at least most of my devices, including the Android device and the Windows device) the files that seemed to have hung in their syncing.
Actually, after doing those things, and unsharing and resharing folders and disabling my VPN, eventually Syncthing made some progress. Or rather it changes its error message. For now I see this:
no connected device has the required version of this file
Once again, Syncthing gives me no indication of what I can do about the problem. Well, the UI does say this: ’ The following items could not be synchronized. They are retried automatically and will be synced when the error is resolved.’ Yet, I don’t think the problem will ever get resolved on its own.
