Updates via The Hub not working

Updates via The Hub are not working across any of my sites (I have 50+ sites connected). Getting error that says could not copy files on every single one I try, even on WPMUDEV's own plugins.

Can anyone else confirm this issue, or provide an ETA on when it might be resolved? I have a few things with fairly critical updates that need to be completed and I'm not looking forward to logging into all 50+ sites separately to do so.
