Kickr Bike v2 overreading

Does anyone having overeading power issue with his kickr bike v2 ?
My dual records between favero assioma duo and kickr18 was very close to +/- 1%
Now, my kickr bike v2 is +4% of my favero assioma duo.
I did several dual record, always same result.
Wahoo said it is under review, but never come back after 3 month.

Hello Francis,

Same for me … 5% over-reading my assioma calibrated using weight.

Did you receive update from Wahoo ?
