GCash Link Leads to Infinite Loading Screen

So, if you try to add payment via GCash in your Apple ID, it doesn't work.

Follow the steps accordingly, but looking up online for some help (which didn't really work) I notice that the moment you tap on GCash as an option, it should swap apps to GCash. Except... It doesn't.

Instead, a sub-tab or whatever it is called pops up, a mini-safari tab if you will. The one that pops up when you click on an ad or something. Anyway, as you do the GCash log-in steps, it will be all for nought for at the very end, you're met with an infinite loading screen. God knows how many times I've retried over and over but to no avail.

This is getting on my nerves, incredibly so due to how insanely unintuitive and irritating this is.

I've set my browser to other browsers such as Opera GX to test, but same results, except this time, other browsers straight up lead to a blank page with nothing on it.

It is so frustrating, and unnecessarily so.
