Well, to be fair that was not a bug report, but a feature request. The change was intentional and the funcionality is still there, but you need to do things a little bit differently, that’s all.
I fully understand your point, because I was also used to use parent limits, but after a few days, I really didn’t miss that at all. However, if using parent limits is important for your workflow, please remember that you can still use scheduler v2 with newer Anki versions
