IOS App not working with TSR 7810 – AV CONTROLLER - US Review

iOS app is very inconsistent, works intermittently. Using with TSR 7810 and it always opens with an error message and an unable to use. Thank goodness I still have the Yamaha remote. WiFi signal is strong and all settings appear to be according to the instructions in the manual. I suspect the problem is with the app itself. Will not launch. iOS app needs to be updated because it is not usable as is
