Error when purchasing credits by card: "too many requests, please slow down"

[EricGT]

Did you see?

You're making too many requests please slow down

Update: I tried again 2 hours later, and it works

or

Unable to add my debit card to start payment plan

“You’re making too many requests, please slow down” This is a common issue, seemingly received when OpenAI itself is making too many transactions by credit card to its processor. The solution is to wait and try again - and maybe we should figure out if it’s some kind of hourly or daily limit.
