That stinks... Sorry to hear about the endless delays on IOS app functionality. Thanks for the heads up, I'll pass that on to those who need to know that... Hopefully I caught it in time before they depended on my advice to buy something; or maybe they'll just finally switch to Android;)
Actually you can get an android Bluetooth device for dirt cheap (especially compared to iOS devices). The cheapest (best) way to get a dedicated device for the MP5's use is to just buy a cheap Android device with just Bluetooth, USB OTG & small screen (+ GPS if needed).
That way you don't have other radios/stuff eating up the battery & just get what you want. For example, an amazon you can get such for under $40. Probably get several days battery life on 1 charge & you can hardwire it into your power systems, if desired!
If you are tied to the apple products for whatever reason, can't have another device & either need or want functionality via Bluetooth with your motor; you can create a VPN & VM to operate the Android app on the apple device with iOS or actually run Android instead of iOS!
Hopefully 1 of these options can help people until the issues are resolved with iOS & the app.
Btw- my advice on Bluetooth devices to run the app... Get full Bluetooth 4.x: not just Bluetooth low energy (there's compatibility issues with BLE only working with another BLE able but not the rest) but full Bluetooth 4.x can do BLE & the rest)... Good luck

P.S. if you get said device, you can also use it to shake enable a highly effective anti-theft element if it has at least some Wi-Fi, GPS, gyroscope/accelerometer, (backup too) camera, etc...
Depending on your programming skills, you could set it up that when left alone (or otherwise instructed)...
(A) Require password to use;
(B) If handled (gyro/accel) it sounds an alarm over Bluetooth (don't wire direct to speaker, cause then if the crook yanks out the alarm, they won't know that's not the entire alarm system);
(C) Lock down the motor with the app;
(D) Take pictures/video with camera: &
(E) Send locating/ID data from GPS whenever there's a Wi-Fi signal...
That's just the basic elements, it can operate as security system, I'm sure there's other things to do also. Just make sure you get sufficient RAM, processing power, storage, etc. to run said system. But if its just a minimal dedicated device with no fancy stuff, you can get cheaper but lower capability device... As always, KISS rules!
