Grid View/Loupe View/Compare View/ Sort/Thumbnail toolbar is missing in Lightroom Classic

Hi there,

Sorry that the Grid View/Loupe View/Compare View/ Sort/Thumbnail slider options toolbar is missing in Lightroom Classic Library module.

Which version of Lightroom are you using and what is your computer's OS?

Click the downward-facing disclosure triangle on the far-right of the Toolbar to see the complete list of tools, and then check the ones you want to be shown. (Make sure that all are checked)

If the entire Toolbar is missing, press T to show (and hide) it.

If that still does not help, restore the Lightroom Classic app preferences to default and see us know if the issue still persists. Please refer this article for step by step instructions:

Let us know how it goes. 

Thanks,

Akash
