要約

Some users are unable to grant permission to Jira within the Teams app

環境

.
Jira cloud, MS teams

原因

Due to a caching issue within Microsoft Teams the review permissions button does not respond or it goes through the steps and loops back to the same screen 

ソリューション

You can perform the below steps:

1. Sign Out from Teams application
2. Re-run application - (Microsoft Teams) needs to be closed via task manager/force quit and reopened.
3. Sign In to Teams again
4. Perform the permission approval

If the above does not help, use the web version of Teams to review/approve the permissions  https://teams.microsoft.com
