@patmead Interesting. I'll need to troubleshoot this one a little bit. The go-chromecast library that I use to communicate with devices sometimes panics when closing connections, which should be fine because CastSponsorSkip has a logic to recover from these. For some reason, it seems like the panic is causing CastSponsorSkip to fail to remove the device from the list of active connections, so it never tries to reconnect. This logic shouldn't ever be skipped, so I'm not sure what's causing the issue yet.
I'll keep you posted on a fix!

Ah I believe I see the issue. When it tries to reconnect, some of the device identifiers get reset, causing it to never be removed.
