Azure Devops Calendar showing blank tiles

Hi @Vijay,

Thanks for reaching out to Microsoft Q&A.

Could you please check below steps and confirm if it works?

1. Check Permissions: Make sure that your account has the necessary permissions to view the items on the calendar. If you have limited access, some information might not be visible. Dashboard-related issues often stem from permission settings, so it's a good idea to verify this.
2. Sometimes, simply refreshing the browser can resolve display issues. Clear your cache and try again to see if that brings back the names and icons on the calendar.
3. Ensure that you are using a supported browser and that it’s updated to the latest version. Sometimes display issues arise from browser-related problems.
4. If any of the Azure DevOps services used to populate the calendar are disabled in your project settings, this could lead to empty tiles. Check the status of your project services to make sure everything is enabled.
