TacX Desktop App drop out

Today I used the TacX Desktop App after long time using a ANT+ usb key.

The signal from the HR band is OK.

A relevant info can be that at the same time I have also my Edge connected using ANT+ in both the session above.

But the signal from TacX NEO 2T continued to drop out.

I'm using firmware 0.0.34.

The same today (the day after of the comment) using BLE connection only.
