Tacx Flow + Forerunner 255. Different values (Speed / distance) and duplicate activities.

I have connect my Tacx Flow with my forerunner 255 watch (Got Cad, Pwr and Spd External Sensors).

Then started an indoor bike activity in my clock and a movie in Tacx app.

In the end I got two different activities in Garmin.

Question 1: Is is possible to get the activities merged? Because in Indoor Cycling activity (Watch) I get Time in Heart Rate Zones, Training Effect information and in the Tacx activity I get Power, Elevation information. I would like to mantaine all indicators.

Question 2: In the 2 activities the cadence has the same value but the speed and distance have diferente values. in Indoor Cycling activity (Watch) I got 20.9 avg speed - 43.76 km but in Tacx activity I Got 26.5 avg speed - 55.01km. Is this normal? Why this happens? witch one is correct?

Thanks in advance

answer for the Q1: https://www.dcrainmaker.com/2021/06/garmin-training-status-now-includes-zwift-trainerroad-the-sufferfest-and-tacx-app-workouts.html i think it should work, probably you need to connect your Tacx account with your Garmin account (in the past it was mandatory)

answer for the Q2: https://zwiftinsider.com/garmin-zwift-distance/ (so it is normal with Tacx app too/all virtual apps work in the same way, with all indoor trainers, these 2 values never be the same, and sometimes the difference is high, sometimes it is not much, depending the circumstances and variables), the reason is the 2 different speed sources, speed of the physical rear wheel vs a computed virtual speed by many variables)
