Hello @lkeyes,

Greetings!

Regarding your concern, I understand one of your agents receives a pop-up to install the MS Teams app even after installing it. To resolve this issue, I suggest you ask the agent to clear their browser cache and cookies. After doing so, they can try logging in to the account again. Also, you can try accessing the account from an Incognito tab to see if the issue continues. 

If the problem continues, I would recommend that you ask the agent to generate the network logs and send them to us via DM. 

This will allow me to investigate the issue further and provide a more comprehensive solution.
