After upgrade to 3.8 runtime, multiple prefabs stopped showing Spine objects in Android.
These prefabs has an Canvas with Overlay render mode.
If I set to Screen Space - Camera with a camera, it works, but this isn't that I need for my app.
In Unity editor works perfect.
Another bug that I found is with RectMask2d, isn't working.
The editor show this warning: "Material SkeletonGraphicDefault doesn't have _Stencil property"
