Problem fixed; I think. After turning off Bluetooth and restarting iPhone and then restarting Bluetooth and manually reconnecting to all the devices, the connection issue was resolved. All the devices indicated “Connected” but they were not. Had to manually reconnect all the devices. Same issue with the car. Indicated “Connected” but could not make or receive calls or play music until I manually turned off and reconnected and then played a song. After that the connection worked.
