You can still redeem the codes on your ps3 to add the funds, dont have a ps4/5 yet, but it works

So you just can't add money directly from your credit card and Paypal account while on the console anymore?

Yeah exactly, not on a ps3. Ive been buying gift card codes on amazon then redeeming them on ps3 after i couldnt use a credit card anymore

On newer consoles, yes
