GCash not linking to my Apple ID

My GCash payment method stop working all the sudden and I had to remove it.

But when trying to log in back it, I go thru all the steps until I end on the “Online Payment Linking Successful!”.

And the I get stuck in this page forever when I leave the page, my account was never linked so I can’t use GCash as my payment method.

Any way I can fix this?

I’ve tried doing this more than 10 times and still had this issue since January.
