ERG mode suddenly not working anymore

Good morning from Vietnam.

Since a couple of days, ERG mode has stopped working. When doing workouts, the power no longer stays at the suggested power and I need to manually try and hold the power required.

ERG mode is shown as β€œon” on both Zwift and ZC.

I run Zwift on an IPad and ZC on android. I use a smart trainer (Magene Gravat) and a Polar HRM.

The only thing that has changed in the 2 years I have been using Zwift is that I recently purchased the Polar HRM. I first thought this might be the culprit but even when I do not pair the HRM, ERG does not work.

Things I have done so far:

  1. Restart Zwift and ZC.
  2. Update the trainer.
  3. Do a spin-down calibration.
  4. Completely turn off trainer and turn again.
  5. Restart IPad and phone.

I could really use some help as I want to finish the ZWIFT Academy :wink:

P.S.: I did contact ZWIFT support but no reply.

Thank you in advance,
