Continue reading on IpadOS stopped working

The problem was that the database file was corrupted.

I encountered the same issue when using with containers. I’m using:
yacreader/yacreaderlibraryserver:9.16.3
yacreader/yacreaderlibraryserver:latest
In both cases, I’m unable to save my reading progress when browsing a newly created remote library on my iPad.

I’ve already sent my .ydb file to the email address listed in the Contact.

Your database was fine, so I think it could be a permissions problem.
