@Gargronis this related to most of the YouTube embeds in my timeline now showing the embed for "monokuma says trans rights" video (https://youtu.be/3G9DQWZpO1M) rather than the actual linked video?
I first thought it was a caching issue with the Fedilab client I use, but I noticed now that it also happens in the web interface of mastodon.social, and not just for my account on my phone, but also for my SO's on her computer.
@Gargron
for example https://merveilles.town/@neauoire/103170821655466907 shows fine on the Merveilles instance, but when displayed from #MastodonSocial (e.g. by searching for that URL in the mastodon.social web UI) it will show the embed for the above trans rights video.
