microsoft lync web app - I click the link to the meeting, the lync web app window opens, a loading icon appears, then disappears and the Lync window is blank

Does anyone else have the same problem in your organization?

Does this issue persist all the time?

Here are a few things you can try:

1. Clear your browser's cache and cookies, and then try accessing the app again.
2. Make sure you have the latest version of your browser installed.
3. Try accessing the app from a different browser or device to see if the issue persists.
