I have a 7 Plus and use T-Mobile. Recently I updated to iOS 10.3.1 (and 10.3.2 beta 5 today) and I can no longer receive messages from a group message if even one person is using an Android device. I restored the phone through iTunes several times and set it up as new but when I go to settings -> messages -> MMS/SMS, group message is completely missing. In the past I had the option to disable/enable group messaging but it's just not available at all. I went to an Apple store and they said it's an issue with T-Mobile and will be resolved when the next iOS update comes out. I really need group messaging to work because I rely on it for work and school but they said there is no option to downgrade back to iOS 10.2? I installed the iOS 10.3.2 beta 5 today because I was hoping that would fix it but nope. Does anyone have any suggestions or advice on what else I could do?
