Music Assistant players for third party Chromecast devices lost power toggle

After some recent update to Music Assistant (currently on 2.8.1) I noticed that my third party Chromecast devices such as soundbars had their MA entity names changed from something like soundbar_ma to soundbar_2. This caused some of my player cards to disappear. That was easy to fix by renaming the devices back to soundbar_ma.

However, these third party devices seem to have lost the power toggle in the MA device.

The official Chromecast devices such as the Google Home Mini still have their power toggle in MA. It is only the third party devices that seem to have lost it. Furthermore over in the Chromecast integration all the devices have a functional power toggle so it seems to be only the MA duplicate the has lost that function.

Does anyone else have this issue?

Update: I think it is this issue.

I experienced exactly the same issue today after the update. The solution was simple in my case: restart Music Assistant via Settings > Apps > Music Assistant. After that, all broken connections with the speakers were automatically restored.
