Using TrainerRoad with Rouvy

Im no expert but in Rouvy’s Just ride mode erg is disabled. Might be completely wrong but do you think its possible that erg mode on TR is clashing with Rouvy? I would try disabling erg in the TR app and see how you get on.
If its a bandwidth issue then you could try downloading the TR workout so it no longer reduces your internet speed.

Like I say Im no expert but might be worth trying if you havent already thought of it
