I am receiving the following comment: Sorry, we can't update your account. Please wait a few hours and try updating again (9999). What should I do?

We can perform some troubleshooting solutions to add a user to your account, idan-iddrealesta. 

There are times when a browser's cache data becomes full of frequent access to web pages or damaged. This causes odd behavior when updating your account in QuickBooks Online (QBO). To better isolate this issue, let's try signing in to your QuickBooks Online (QBO) account using a private or incognito window. This mode doesn't use the existing cache data and helps us confirm browser-related issues. Here's how:

• For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Option + P

Then, try updating your account again. If you are referring to updating payment and firm info, see the Update billing, subscription, and firm info in the QuickBooks Online Accountant article for the steps and details. 

If it works, go back to your regular browser and clear the cache to delete those temporarily stored files and browsing history. Web-based platforms like QBSE collect cache files (cookies) to save you time, but this can impact processes and cause them to not work. You can also use other supported, up-to-date browsers to roll out the possibility of a browser-related issue.
