I noticed something a while ago I think I reported it at the time but I might be wrong (I’m getting old and forgetful 😆) so bear with me.
I think I might have noticed a situation where I accidentally made some performances In RM with the KPA Broswer Mode. In this case the performances saved automatically. however, when making a performance with the KPA set to Performance mode I had to physically store the performance. I wonder if this did happen (or is just my imagination).
FarleyUK could you try making a performance with the KPA set to Browser Mode and see if you get this behaviour. Its maybe a long shot but it might help find the root of your problem.
I'll try, but I NEVER use browse mode... I always stay in performance mode.
