I have a Smart Hub 2. I have noticed that a number of things on my iPhone no longer work. The Findmy app works on 4G, BT minihub, Vodafone and Sky, but doesn't work on the Smart Hub 2. I cannot send or download picture messages in messenger, but text messages are sent and received. On the app for my CCTV system, I don't get thumbnail images of recently recorded videos, but I do if I switch over to 4G. I cannot change my Apple ID via wifi provided by the Smart Hub, but I can if I change to 4G. Please let me know if you have experienced one or more of these issues and, if so, have you found a solution.
Thank you for your suggestion. Did you have a similar situation and resolve it by turning off smart set up?
No, but Smart Setup is the cause of many a problem and is the first thing you should turn off when receiving an SH2.
