Hi

I just did an OIS upgrade on my iPhone to OIS 15 yesterday and my Fitbit Charge 3 won't alert me to texts or email either now. I've reset the Fitbit and the phone 3 times, disconnected from Bluetooth, reconnected, synced twice, all the messages and emails boxes on phone and Fitbit are on and notifications set to allow, but nothing. Please can you help?
