I guess y’all are suffering from a bug that I can’t find categorized publicly. I’m not running eDrive currently to help. Users who want reliable file sync should reach for nextclouds client if they can’t sit it out.
If you want to debug, see the #7740 comment (and those further up by Vincent) on how to get some introspection into eDrive ongoings.
That issue-ticket isn’t necessarily your bug, the comment just has comprehensive debug instructions.
