Hi, after change to bluetooth. I had one drop signal, but disconnecting and connecting in menu zwift do not give result. After that i tired on/off bluetooth service without closing zwift and that solution worked (in windows 10 right sidebar on screen).
BTW: I buyed new strap for HR , and works. I have signal and data on Bluetooth connection. Update my Tacx Flow frimevire.
So now everything works fine. For now.
