It truly is odd. I am not aware of any bugs in the database. I have Diarium set to back up to Google Drive, but I am not sure where in Google Drive it is backing up, as I don't see anything obvious in terms of a folder or file.
I have no problem allowing you access to my journal database, but not sure how to privately give you that. And yes, all the other trackers seem to be fine. Nothing odd there that I can see.
As part of this discussion, please let me know what I need to look for in my Google Drive that represents the Diarium backups. At the same time I will look into the other options to backup my Diarium.
