Hi!
I have the same problem. Opened a TAC case, because since the last update on Aug 02, my switches show up as not in sync and since then I cannot push down any config.
Thought about reprovisioning the switch. Download running config through cli, then unassign subscription and delete switch from monitoring. Then add the subscription and import config to new group. If you are thinking about doing this DO NOT DO IT! "Import config" button is grayed out since the last update. TAC assured me, that development team is working on getting this feature back. Until then I will not delete switch from central, since I have a few config parameters that have to be imported through the cli running config (like MSTP config).
Its an ongoing TAC case. If I get update then I will share it with you.
