Access Denied" errors when accepting QuickBooks invitations, advise

This sometimes happens when the invitation link has expired, or there's a conflict with your current browser session. To fix this error, open the invite link in an Incognito or Private browser window, or switch to a different browser altogether.

If the issue persists, you may also want to ask the person who sent the invitation to reinvite you, and then accept the new link in either a regular or Incognito browser window.
