Garmin Instinct Solar and Zwift - problem

Hello,

Recently i wanted to register my free ride in Zwift with Garmin Instinct. Before launching Zwift I added separate cadence sensor, HR sensor and Elite Direto XR-T to Sensore and Accessories menu. Trainer was found as Spd/Cad - 8777. I went into this sensor and added Wheel Size 179mm (auto shows crazy values). Then I started Zwift, launched Bike Indoor activity on Instinct watch. Unfortunately speed was showing only time to time, mostly I saw only horizontal lines instead speed numbers. I deleted all found sensors repeated procedure, but effect was exactly the same.

Fenix 7 has no problem at all to work this way, but it looks soft there is more sophisticated and can find trainer as Direto.

Do you have any suggestions how to solve this problem?

Regards Rafal
