TextMesh Pro TMP label flying away to center of the map on iOS build

Hello!

There is a trouble I have with TMP (TextMeshPro - Text) on iOS build. Label lies on the road with Rotation Vector3(90,0,0). In unity scene and mac build it is all good, but somehow on iOS build Rotation switched to Vector3(0,0,0) and flew away to the center of the map (see StrangeBehaviour.png). How could it be? How to fix it?

Thanks.
