Tactix 7 fw 26.09 is unable to work with HRM 600

I can pair it via BLE, but it can't download the activity data:
Cannot download HR data over BLE. Switch to ANT.


But no way to pair in ANT mode:


It offer "Yes" only. No way to "keep using ANT because BLE can't be used".


Conclusion ? It can be paired in BLE mode only, but data can't be downloaded using BLE. It can't be connected in ANT mode. 

So how to use the expensive sensor with expensive watches ?
