Making a skeletal mesh with more than 8 bones makes it invisible in Mobile Preview

So I’ve been making a game, and I’ve noticed that if a skeletal mesh has more than 8 bones, it will be invisible in the mobile preview. Because this amount is so small, I’m wondering if there is any way to exceed it and still have the mesh visible. So, I’m wondering if it is possible to exceed it, and how, if it is.

Because a maximum of 8 bones is definitely not enough.
