Since a few weeks, in several of the git repos the default master (or main if this is the master) at the remote server is not available and visible by default anymore. I always need to first "update branch" during pull or push. Only then the master is visible, but still needs to be selected manually. Unfortunately, this then forgotten after the next commit and I need to update and select it manually again.

In the past, these branches were always available. There are some repos which are not affected.

I also tried to remove the repos and pulled it new, but did not help.

Any ideas how can I back the expected behaviour?

Thanks!
