If a fediverse post contains something that the receiving server doesn't support, we need a defined way to show that to the receiving user. For example if I make a pixelfed post with 6 photos and mastodon only shows 4 of them, there needs to be a way to signal to the receiving side that there is content they can't see. This has been an issue forever but one of those little edges that makes the whole experience worse for everyone. cc
@88bb4b71…4c0a6ef7 any ideas for how we could make progress on this?
