That was released quite some time ago.
This thread has additional issues:
Within this thread, someone advised to roll back to an even earlier version. Worrying that the current informed advice is to roll back to a version released in April'24 to rid yourself of the problem.
However, it now seems these issues have finally hit some kind of critical mass and a beta sounds promising. Something clearly changed in 2.3.9 which has caused major issues for quite a few people, manifesting in a manner of ways, but somehow (I assume) wasn't picked up by the beta group?
I really don't wish to join, but I am curious as to just how many people are involved.
