Why can’t I see my gift card when I try to buy something through my Xbox?

When I add gift cards on my xbox account, I can’t see it on my ps5.. For example I redeemed a vbucks cards on xbox and it not showing on ps5

Very similar problem, I purchased a €5 gift card on Friday to test whether I could buy an Xbox with it on the Microsoft store. It worked, so I told my friends to gift me those gift cards. I redeemed a total of two gift cards worth €20 each, both of which
do not show up When trying to purchase a console. There it only gives me €5. When trying to purchase a game, it shows me €25, which is still €20 short. I talked to Microsoft support yesterday evening and we went through some steps, but sadly it did not work.
So I can’t use the €40 gift cards as expected, and 20 seem to be entirely lost somehow.

Hello, when i try to purchase through roblox, it only gives me credit card/ gift card options. If i try buying through the microsoft website, it says it requires an xbox and i dont have one.

What alphanumeric code? I'm trying to buy a gift card with reward points not use a gift card. I can't get a gift card because it won't accept the reward points. I shouldn't need a phone number when I'm purchasing on my console. I can buy games on the store okay using my credit card without messing about with phone numbers and emails.

I've tried buying the gift card on this site on my phone but it won't process the mobile phone number I enter. I've even tried my 2nd mobile.

I have £10 of reward points but xbox won't accept them. Why can't Microsoft just send a gift card code to my email? This isn't an uncommon problem, thousands are experiencing this nonsense.

At this stage, I think I may as well sell my xbox and stick with Nintendo.

I put money on my xbox with a gift card and when I go to buy items for games it says I only have £0.09 I dont know why considering I put in a £25 gift card what do I do to fix????
