Hitting rate limits but can't upgrade account: 'Unable to save billing info at this time'

Hello there,

I’m trying to upgrade my account following the new Docker rate limit rules.

However whenever I put in my card details (tried with several different cards) I have an error saying ‘Unable to save billing info at this time’.

It’s very annoying as I have some cases where the rate limits are breaking my CI pipelines, but I can’t upgrade.

Any ideas?
