Hi Timo,
the change started with january 2023, the older entries are not affected.
I checked and this seems to be partly my own fault:
When setting up the new MacBook, I was not aware (anymore), that WorkingHours creates it's own "WorkingHours"-folder on the WEBDAV-path you enter, so when configuring the path to the shared DB, I ended up with two databases in two nested "WorkingHours" folders.
When I noticed that sync did not work, I tried to change the path on two devices and manually deleted the unwanted database path - and the thing went wrong.
there is one request I'd have: I found it difficult that there is no way to revise the existing sync-setup (URL, path, user credentials); There is only the option to reset the credentials altogether. It would be helpful if you could see and revise the configuration, or to be able to read it as to copy it to another device.
One thing I noticed during the whole process: although I use a webdav drive of my internet provider (never used iCloud, as it was not available at the beginning), in the iCloud system settings WorkingHours is set to use iCloud (by default ?). would this interfere with the wedbdav sync?
thanks anyway for the quick reply and this very useful piece of software!
PS: feature request: I would be cool if one could combine groupings of the work units in two stages: i.e. monthly AND daily groupings (Incl. the respective sums of hours/wages), as to get a better overview.
