Connection delays

For the past month or so it can take me anywhere between 10 minutes and half an hour to get Zwift to get a signal with my Tacx (via Bluetooth). I can connect the turbo easily enough with the Tacx app, but Zwift it is really a bit of hit and miss with having to keep coming out and launching the app over and over again until it eventually gets a signal. It even struggles if you exit the game and immediately try to relaunch it. Problem is still occurring even on the latest update. I’m on Android.
