User’s app not updating

My app’s URL: Smart Choice Benefits

I’ve created an app for my father in laws insurance business. A few months ago we removed a button allowing users to enroll new clients, but there are still a couple users with the button available, and working, on their app. A majority of users have the button removed, but what could be happening here?


Is the button completely gone, or is it disabled with a visibility condition?

If the button was completely removed, I’m wondering if they still have an old version of the app cached on their device. If it’s part of a visibility condition, what is the condition you have set up? Do you happen to have another version of the app that uses the same sheet?
