Able Ability System Info and Support Thread

@ where goes DynamicBranchAbility and OnGetBranchAbility function? I’m using combo system which need to pick which ability to branch to and I see that in new version there is no dynamic branch…

I see there is FGetAblAbility - but how to use it in C++ not in BPs?
I have my own Ability class (in c++) extending from UAblAbility and earlier I could just override OnGetBranchAbility function and point to my combo system.
