Hi again and sorry about the delay! While the Silky Smooth update probably set a new record low for number of things broken by an update, we've still had a fair number of messages to keep track of in recent weeks.
We've unfortunately not been able to diagnose this issue yet, but I wanted to let you know it is being looked into, even if we haven't written back. If there's any new information, don't hesitate to post it here, and thanks for the details you already provided!
