The only solution ... keep mailing, tweeting reminding Jan Ole to fix this youtube problem.
And there are other very important issues, like the transition from Twitter profiles from a 32bit to a 64bit UUID, which gravity can't use, so that more and more user profiles are unreachable for gravity users!
Those profiles won't be listed as friends, as followers! Their tweets, mentions, replies, or DMs won't be listed!
Please keep contacting Jan Ole to bring him to fix those problems quickly!
