BLE FTMS service not recognized with Fenix 7s

Hello everyone.

I am implementing a sensor for my crosstrainer with a nfr52840 board. "Track my indoor workout" android app can see it as ftms, BLEScan can see it and connect, but Fenix 7s do not find any new sensors. Could anybody help me understand why?

Thank you
