How can I force a decrypt?

Operating system

Android

Joplin version

3.2.7

What issue do you have?

After syncing, sometimes I end up with a small number of notes that remain encrypted. There are no errors, sync completes ok & log file shows no errors (just now only one "Note editor: Code Mirror error ..." which I assume is not related to encryption), but I still have some encrypted notes. Sometimes Joplin will resume (continue?) decryption after some seconds, sometimes it won't (or much later, I cannot tell); so I cannot tell whether it has given up or is pausing.
.
So at some point everything is in fact decypted, but it appears to be nondeterministic. Any suggestions what is happening here; any way I can manually "enforce" another decryption run?

Cheers,
kai.
