I think there may be problems. Looks like there is a bug with 0.19.0 that may be affecting us. I made a post in a local sub and checked later from a login to a different instance and I don’t see the new post.
0.19.0 has a critical bug where sending outgoing activities can stop working. The bug is fixed in this version. It also fixes the “hide read posts” user setting, fixes a problem with invalid comment paths, and another fix for private message reports.
