Let me help you invite the new user to your account, delivery-naritha.
It's possible they didn't receive their invitation or their invitation is missing. If so, we can resend them the invitation by following the steps below:
Then, resend the invite:
If you don't see the option to resend and the status shows Active, it means the user accepted your invitation to join your company and already set up a login. They can now log in to qbo.intuit.com and start working on your QuickBooks company.
If the same thing happens, 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:
Then, re-invite the user again. If it works, go back to your regular browser and clear the cache to delete those temporarily stored files and browsing history. The overtime collection of data can create corruption, however, removing this should fix the issue. You can also use a supported, up-to-date browser to roll out the possibility of a browser-related issue.
