I can confirm the previous comment.
Since the October 1, 2022 Patch/Android upgrade to the Chromecast with GoogleTV HD, buggy is an understatement. They have been unusable - dropping frames is the least of the issues. Audio and video often get way out of sync (not a little out of sync) and video becomes unstable - on numerous apps, after numerous device resets and on multiple devices of the same kind. I have very fast fiber internet - the problem is not on my end. Switching out to older Firesticks solves all issues.
Google should be ashamed of this product with this firmware and should have addressed this problem immediately. It's six months later - and - nothing.
Buyer beware - stay away from these - the HD versions at least. I have not tested the 4K versions.
