Why is my matic not showing on Polygon?

I've been scratching my head over this for quite some time now. I've transferred my MATIC tokens to the Polygon network, but they're just not showing up in my wallet. What could be the reason for this? I've double-checked the address and the transaction ID, and everything seems to be in order. Could it be a network issue? Or is there something else I'm missing? I'm really hoping you can shed some light on this for me. I've been eager to start trading on Polygon, but this has been a real roadblock. Any help would be greatly appreciated.
