I am seeing this too, but I have yet to find an exact way to reproduce for a bug report.
If someone can find one and report back in this format maybe a fix can get traction.
Basically, Once I’ve been using the program for a while, in order to disengage the the suspending of auto-scroll I have to zoom out enough to reveal the transport cursor, and then hit F.
Or quit and restart the program (without actually deleting prefs.)
