My Sterzo worked correctly until the last update.
After updating I can still see it and pair it but it does not work in game.
With the new update we can now also enable in the Zwift Play left and right at the same time as Sterzo, and the Zwift play work.
At least once after enabling all three (Sterzo and Zwift Play left and right) all three worked correctly.
But I have not been able to replicate that. Only see the two Zwift Play, even though the Sterzo is also enabled.
Replaced the batteries in the Sterzo just in case, but no difference.
