Some users can't redeem Google Play credits right now
Google Play checkouts are broken for some people making purchases with Play balance
SIR, DO NOT REDEEM!
If you ever have a scammer ask for a Google Play card send them this. It will waste their time. I did it once and it made them very angry.

YOU DID NOT HAVE TO DO THAT!
I recently had about $40 of Play Store credit that was inaccessible to me for weeks. Google support just kept telling me "Okay, wait 24 hours and it should be good now."
FINALLY someone got it straightened out, but during the course of it, I had to explain to support what Stadia was and why I didn't have a gift card number.
"Guess I'll have to end the Google Play credits program 🤷♀️" - Google, probably
So the TLDR seems to be:
live by the google, die by the google
