YouTube is starting videos with delays and/or interruptions on my Apple TV 4K

The YouTube app on my Apple TV started behaving erratically a couple of months ago. When I start a video. most of the times there is a delay, sometimes even a few seconds of black screen, and the video starts a few seconds from the beginning. Sometimes, not always, this also happens in the middle of the video. When an ad cuts in, this repeats again and is sometimes happening three/four times in a row. I tried with subscribing to YouTube, so no ads, but the problem did not go away. Uninstalling, reinstalling, restarting did not help.

Searching online, I can see people have been reporting similar issues as far back as two years ago. In my case, I only started having it recently.

In another Community discussion from the past somebody commented that it is not Apple's responsibility but rather Google's. I disagree. Running the YouTube app on my Samsung TV and not on the Apple TV I have no such problem, so Apple has at least a part of the responsibility.

Has anybody found a solution or a workaround?
