Erg/Auto mode in activities

Hi guys.
When doing an activity in erg mode or auto the power is all over the place with my Elite Zumo trainer
Do I need to calibrate the the trainer in the app somewhere?
Is anyone else having issues with the app keeping a constant power in erg/auto mode?


Works fine here - first check that it’s not a ‘mixed mode’ workout (which automatically switches between erg and slope). And that you’re not accidentally trying to control the trainer with two devices causing a conflict.
If that’s not it, would suggest writing to support directly via email for specific issues
