I am getting the following error message on Customize the Home Page: Ensure that you moved the Case object from the Available column to the Selected column. I have done the task several times and continue to receive the error.

Hi @Jacquelyn Middleton ,

I've had the same issue, but I managed to solve it. Be sure to take every step like in trailhead description, if you miss something you will get the error about "Cases" in Selected column  For me the issue began when I missed the step with naming the "Recent Items" label to "Recent Cases", so after you try numerous times your browser cache gets cluttered and even if you do it right you get the error, so clean up the browser cache and history, and after that make a new playground and follow every step and it'll work
