When iSponsorBlockTV is connected to an older Chromecast (non-Google TV), the YouTube app on my phone loses the ability to change/load a new video on that Chromecast after a video has been playing for a while. The Chromecast itself keeps playing the current video fine — but attempting to cast a different video to the same device from the YouTube mobile app silently fails to take effect.
Casting a new video to the Chromecast from the YouTube app should switch playback to the new video, the same as it does on a Google TV device paired to iSponsorBlockTV, and the same as it does when iSponsorBlockTV is not connected to the device at all.
Some log of the events when I tried to change the app, not sure if relevant but added it anyway:

Describe the bug
When iSponsorBlockTV is connected to an older Chromecast (non-Google TV), the YouTube app on my phone loses the ability to change/load a new video on that Chromecast after a video has been playing for a while. The Chromecast itself keeps playing the current video fine — but attempting to cast a different video to the same device from the YouTube mobile app silently fails to take effect.
This does not happen on a Google TV Streamer paired to iSponsorBlockTV, which behaves correctly in the same scenario.
Steps to reproduce
Expected behavior
Casting a new video to the Chromecast from the YouTube app should switch playback to the new video, the same as it does on a Google TV device paired to iSponsorBlockTV, and the same as it does when iSponsorBlockTV is not connected to the device at all.
