Hi Patrik,
since I deleted the old log and reenabled the logging, even after a restart of AM, it updates everything perfectly. In the old log there were many errors, but now they are all gone. Sorry, forgot to wrote them down for you.
So, it seems this did the trick. Everything is fine now

Hi and thanks for the update.
In case you run into the issue again, please note the time and send me the log files. I've added a bit more logging in the latest release to be able to track better. Thanks!
