I've been seeing a lot of startrek.website shares I do showing the wrong desc and image in the unfurl on the posts lately. It was a few of them a week at first, but it's become multiple a day now.
As the most recent example, the "Look at the time, its 7 of 9" post unfurls like this in signal:
Is this a known issue? Is there a better place to report instance issues? It kind of looks to me like UUID reuse leading to new posts displaying old images.
Yeah, it's a thing with federation - I see it on Mastodon from time to time.
I've raised it with the Lemmy devs, and they suspect it's some kind of caching issue that will be fixed in the next update.
We hope.
Thanks for the info!
