I have looked in the apps folder and named the files as the appear in that folder
The names in the apps folder are not the names the Linksheet uses…
Your Linksheets should be named (case and space’s sensitive)
ABC iview
YouTube Leanback <--------- that’s the “new” youtube
YouTube <--------- that’s the “old” youtube
EDIT: You will have to apply the Default (Grid) Theme … to get the proper text labels (as above & below) to name your Linksheet.
