Family members have all installed iOS 10 Public Beta 1 - various devices: 2x 5S, 2x 6 and a 6S All have worked fine except one of the 5S models and a 6S The troublesome 5S and 6S can send iMessage texts with effects, (we can all receive them OK, even in a Group chat) but don't see the effects other send. We've also sent iMessage effect texts to them directly and no luck either. What's even odder, is if I send a regular iMessage text it goes through as iMessage, but when I send an effect text, it sends as a SMS instead. Completely puzzled by this! Any ideas?
