Ios S3 sync problem

Operating system

iOS

Joplin version

13.2.5

Sync target

S3

What issue do you have?

It used to crash on ios when I tried syncing to oracle object storage, or even hit check synchronisation configuration.

I tried again today. Hitting check synchronisation configuration would return success. But once I tried to actually sync, I got error "signature does not match could not upgrade from version 0 to version 1 the required information to complete authentification was not provided".
