The scenario that is failing:
- User logs in to O365
- Goes to App Launcher -> clicks custom tile
- Gets Access denied message "Access Denied. You don't have permissions to access this resource. Sign in with the account provided by your work or school to use with Office 365 or other Microsoft services."
The scenario that works:
- User logs in to O365
- Clicks on SharePoint icon on the home page and goes to SharePoint home page
- Goes to App launcher -> clicks on Custom tile
- The page loads fine
Please let me know if there is any workaround or solution for this issue
