Update, after some time of testing and modifying, it seems that it's not the issue

Sorry for just seeing this was asleep when you replied. Now that I look at it maybe it could have something to do with it? fromUser and currentUser should both represent different PFUsers.

You are right. In ProfileSummary.swift I forgot to put `.environmentObject(ModelData()) in the ProfileSummary_Previews struct. Thank you.
