I'm afraid there is not enough information to help. One observation: your spine-unity version (3.5.xxx) does not match your Spine Editor version (3.7.94). As a first step, please make sure the versions match. Next, I'd suggest you try running our spine-unity example scenes on mobile. If those work, there's likely something wrong in your specific project. In this case, we'd need a way to locally reproduce the issue, which means we'll need a small Unity project from you that demonstrates the problem.
