ANT+ usb stick and android

I’m tring to run Zwift using my Samsung Galaxy tablet and a Cyleops trainer. the trainer uses Cycleops’s ANT+ so requres the use of an external USB stick and wont function with the tablets internal ANT+ sensor. I’ve attached the usp stick and installed the ANT+ plugin, ANT+ USB service and the ANT+ radio service. The set up worked perfectly one time. the HR, Power and Cadence were prerfect, but i have not been able to get the power meter to connect since. I’m guessing there is sme conflict between the internal ANT+ sensor and the services I’ve installed? Can some one give me advice on how to propertly set these up together?
