Virtual power not being recognized above 260 watts

Using TR with a mag trainer with a Wahoo speed sensor and a separate cadence sensor with an Iphone 7. When I need to ramp the watts up to above 260 my TR app is not recognizing my sensors and the watts drop fast and the cadence starts to drop as well. If I back off the watts, the sensors get reconnected. I make sure to pair both sensors in the TR app before each workout. Any thoughts on why both sensors are losing connection… Should I make sure the phone is seeing both sensors in the bluetooth area of the phone? I have noticed at the bottom of my phone screen, it only shows one device connected, but if I look into the device screen, it does show both of my sensors connected. This little gremlin is making it hard to get my workouts done properly. Any help is greatly appreciated.
