Resource Calendar (show_resource_schedule) is not showing User Name and Entries for specific User. The normal My Calendar Application works
This was happening due to the user having a custom Schedule without any Schedule Entries.
We recommend removing the invalid schedule so you can use the Default one.
1. Navigate to User Administration > Users
2. In the "User ID" column search for the affected user and go to the record
3. Change the View to "Resource Manager" (3 horizontal line hamburger button at the top left)
4. Clear out the Schedule field
5. Save the form and test. You may have to clear you Browser Cache if it is not reflected right away
