We are trying to change our billing information action and keep getting an error message

Hello there, @angela37.

Providing us the exact error message when you try to update your billing information is very much appreciated to give you the best solution for your concern. 

When you update your billing and subscription, then you got an error code- 81623, there's an ongoing product investigation on that. 

Our product engineers are aware of this, and working to identify the cause of this issue to provide a solution, and will notify you with updates regarding the status via email.
