Client area sending us their QB invitation as user, but unfortunately when ever we click on the invitation link, it display invalid link.please can some help me

Thank you for bringing the broken link in the user invitation email to our attention. Let's check to see what's going on, @uma-hdacc-co-uk. 

Something might have happened on the email you sent, so it's worth to try sending once more. Jus remove the pending invitation, and send another one. However, If it's the same thing, you can send one to a different person you trust to see if the behavior is just happening to one email or not.

If the above instructions do not work, please have the recipient do the initial troubleshooting steps, like opening the link using a private or incognito browser and clearing the cache if that doesn't work. 

Keyboard shortcuts for opening a private window:

• Safari: Command + Shift + N
• Google Chrome: CTRL + Shift + N
• Microsoft Edge: CTRL + Shift + N
• Mozilla Firefox: Shift + ⌘ + P (on macOS) or Shift + CTRL + P (on Windows/Linux)
