Trainer freezing when using play controllers on ATV via companion app

Hi all, has anyone else noticed any issues with trainer reading freezing/ becoming very laggy when using play controllers with companion app to bridge to ATV. Almost as soon as i connect play it becomes noticable how much slower the power reading from trainer becomes. Normally use Neo with hrm connected and controllers, but even if i remove hrm and connect just one controller it happens but as soon as i switch controller off trainer rwadings return to normal. Have tried to different phones and same problem occurs on both. Also updated controllers and its still happening. As it only occurs with play controllers on I’m wondering if there is a priority given by app to zwift hardware and trainer is being somehow blocked. Any suggestions or am I going to have to suck up the £100 spent o n controllers as waste of money?
