I have added my application to the iTunes Connect and allowed the application to go Testflight Beta testing. However, when I tried to send the invitation email to the internal tester, the email, which should contains a button to open the URL from the Testflight app appears to be not clickable, and when I tried to right click to get the hyperlink, it does not have it.

I have tried to remove the internal tester from the Users & Roles section, re-adding the user as internal tester, as well as remove the tester role, adding it back again to get a new invitation email, but all the emails have this same issue.

Thank you.
So, after some time, I did tried on the alternative mentioned by @WilliamCorncobDecker that I eventually opened the email in a web browser. However, in my case, the button is still not clickable. So, what I did was to view the page source and get the invitation URL and send to URL to my device.
Open the URL from the device, and it's working fine now.
