Four additional hotfixes have been implemented. If you have previously installed hotfixes for 3.5, or if you are experiencing any of the symptoms documented in the head post, please apply the latest hotfix files.

Just wanted to say THANK YOU, @rigpapa, for your thoughtful attention to detail. The new “Stop Sign (!)” icon – that I saw for the first time today in “Activities” – really saved my bacon by bringing my attention to a couple of place where I’d forgotten to update a device selection.

This, after almost a week wondering why my dumb Sonos’ volume kept NOT RESETTING every night as instructed, and thought I had updated that device everywhere. Apparently not! :slight_smile:
