Test cases not showing in test player after reverting jira’s permission scheme

Hi, I use Zephyr Scale in my company and we have more than 1000 cases.

We changed jira’s permission scheme applied to our Zephyr Scale project. And then we found a problem so we reverted the permission scheme.

After reverting Jira's permission scheme, when opening the Test player, the error message "Test cases are not being displayed. They belong to another project, which you don't have permission to view" appears and I can’t see test cases in the test player suddenly. 

It's been a few hours since I changed the settings back, but the situation hasn't changed. Does it take time for the permissions to be reflected?
