I am trying to install an app (Mass Edit) and make some very simple modifications to my sandbox. I successfully installed the app and have gone into the Object Manager for Contacts and followed the instructions to make the buttons appear - it now looks like this:
As you can see, the "Mass Edit" and "Mass Update" buttons should appear on the List or Search layouts, like so:
However, here is what my Contact page looks like:
So the buttons aren't showing up.
I don't think the problem is on the app's end, because it has overwhelming hundreds of positive reviews. Is there another step to this process that I'm missing? Any weird permissions I need to activate?
Thanks so much :)
