Help!

So i re-textured an avatar and got it to finally upload to be quest 2 compatible. Everything works find except for one thing. THE HANDS!
gestures are toggled on but are stiff and wont move with my movements. The controllers work as is but the hands just aren’t moving

What can i do to fix this?

maybe you have an issue with the model’s armature ?

How do I check that? I’m fairly new to avatar making and I’ve been trying everything to fix it
