Tax fluks fails to set power

Dear Zwift

Since approx one week I my Tax flux do NOT respond on zwift power.

I am using Ipad to run zwift over blue tooth and it has run fine for 0.5 year.

Speed, power and cadance is transmitte correctly.

When I run the tax flux with the tax app I Can Control the power from the Ipad.

Do you have any idea what coulis be the problem?
