Gift Code Network Error?

Just started playing to have a new casual game to occupy some time with. The gift codes that multiple websites say are available and not expired don't work. Nothing works with the gift redeem window. All it says is 'Exchange Failed. and below that "Network Error".

Android mobile.

Clearly I can play the game on any of my devices. Everything else is working. Other games, web browsing. I cannot find any help anywhere on the internet. Everything tells me "Oh its just your internet failing!" but like I said. Everything else except for the gift code exchange is working perfectly.

I assume the web connect alternate window that your transitioned to when you hit the exchange button in the game has some sort of issue with communicating with the phone system itself or the pokemon unite app. How or why the gift code exchange window is disconnected I don't know.

Is this just a random me problem? I don't see anyone else having this issue? And again the only fixes tell me to check my internet connectivity which is clearly not the problem with my devices.
