Cant buy apex coins on steam

What happens and the order it happens.

This all happens every time I try with one exception, at some point during my trying to get it to work the steam purchase page wouldn't open either but this only happened 1 out of maybe 50 attempts.

1: I go to the store page.

2: I click on the purchase Apex coins tab.

3: I select either the 59.99 Euro or 99.99 Euro.

4: The steam purchase overlay opens, the authorize purchase page. I already have over 100 Euros in Steam funds that are not being held by Steam for any reason.

5: I press authorize and the steam overlay closes and brings me back into Apex Legends.

6: Nothing happens, no steam funds are deducted and no Apex coins show up in my account.

I've tried the following;

-Restarting my PC.

-Restarting steam.

-Reinstalling the game.

-Launching Steam as admin.

-Verifying game files.

-Turning off the steam fps counter. (saw it on another thread of a similar issue)

My steam store is set region set to Denmark which shouldn't be causing problems.

I will not try purchasing the funds through the origin client since I added the funds to my Steam wallet for this sole reason and have nothing else to use them on.

Thanks in advance.
