If you're from the UK, check the Online Safety Act.

thanks for your reply yes I am from the uk and 70 years old if I cant add games to my wishlist how do I buy them

A credit card is required for age verification due to the Online Safety Act that came into effect.

they have my credit card info

Is it attached to your account or do you just enter it when you do purchases? The former is required now.

I'm from the UK, 60 years old and don't use credit. Steam has my debit card and credit in my wallet, and I've just been blocked from games I've already bought from Steam. They need to sort out how the new act is applied or lose a tonne pf UK users!

Exactly the same as me. I've been with Steam, from the same place of residence, since late 2003, using the same bank account (which I have had since I was 10) and the bank's own debit card. I checked my Steam purchase history today, which goes back as far as 2009 at least. (Maybe earlier history isn't kept.)

Now, I know it's ultimately the idiot UK Government's fault, but Steam knew this was coming a LONG time ago, and THIS is the best solution they could come up with in all that time? Actually, that lack of foresight and planning sounds just about right for Steam. 😄

I haven't owned a credit card in over 30 years, and I'm not about to get one just to keep using Steam. Looks like "Hello, Epic Store!" from now on, for me. All actual kids will do is ask a parent to buy the games for them using a credit card, because most parents don't give a toss about Steam or what games they sell.

This probably is an obvious one already checked, but have you checked for Steam Client Updates? Have you tried different sources (PC, laptop, phone, browser) to use these functions? You might also take a look at your ad blocker/PC security/VPN and see if one of those is causing the issue.

Also, you don't need a game added to your wishlist to buy it.
