i think media posts from 1.6.1 aren't federating right to 1.6.0
@InspectorCaracal crom's posts were images
@squirrel *looks*
okay I'm running on 1.6.1 minus like, maybe a couple commits, and it's showing as an attachment instead of inline for me as well. Let me go see what those commits are.
@squirrel @InspectorCaracal i'm on 1.6.1 and it's the same here... though i have seen this happen from crom in particular on other occasions in previous versions
@squirrel All media posts or just videos, do you know? 1.6.1 included a new video player
