Gen 4 apple box not working

Hello - I recently upgraded to apple Gen 4 just so I could use Zwift on the big screen. It worked great at first but now I’m having issues. The watt reading is very inaccurate, as is the RPM’s , there’s so much tension I can barely get through a warm up. I’ve deleted the app a few times and reinstalled and that hasn’t worked. I’ve also calibrated with tacx app. I got so frustrated this week I switched back to mini ipad and it was smooth sailing…however I still need to figure out the apple TV app, it’s the only reason I bought it. Any ideas??




Are you sure you are calibrated properly and then have killed the connection from your phone to the Trainer as the Tacx app holds the connection which can interfere with proper pairing.
