Dream Air: Do someone also uses the headset with contact lenses and eye tracking?

Hi, I've got my dream air slam headset. I tried to calibrate eye tracking many times, with different IPD settings, with different position, with a good sweet spot. But each time I'm getting the error message. "Failure, because eye movement is too different to graphics movements.".

I have to wear contact lenses due to kerataconus. By my Galaxy XR the eye tracking works well. But dream air wont. I opened a ticket, but i'm unsure, is the issue by headset or by me some how?

Does someone uses pimax headset also with contact lenses?

Thanks
