Hi, I bought a Nokia 6 specifically because it had Ant+ support. Everything worked OK on Android 8.0 but after upgrade to 8.1 Ant+ stopped working. I have Ant+ Radio Service installed and have tested with Ant Tester, which states everything is OK except it says Built In Firmware has no service.
I did contact Nokia support but they were no help.
Same problem, Nokia support did not help me.
