Smartsheet Microsoft Teams Integration Error

I am currently experiencing an issue with the Smartsheet application within Microsoft Teams.

When I first added a Smartsheet Reports as a tab in Teams, I logged into Smartsheet via Teams and the reports functioned fine until I restarted my computer. Now when I select the tab the message "Please log in to your Smartsheet account to access this published item" is displayed. Upon selecting Log In, I am redirected to my default browser, but no page actually loads. Teams still displays the same message.

The only way I have found to log in again is to delete and re-add the tab every time I wish to use it.

I have reach out to Microsoft, but they have been unable to solve the problem yet. Wishing to see if anyone is aware of a resolution.
