Is there any problem with the last iOS 15.1 update and using the dual band HR with your TACx Neo 2 T??

I updated the iOS of the iPhone and now the TACx app allows the dual band HR to connect but doesn’t show the HR measured. Is Garmin looking into this? I have to iPhones 11 and the one without the update of iOS still works. I contacted apple and they requested me to contact the Garmin so that they can update the app in a way that works.
