Buttons created in Adobe Acrobat Pro not working in Mobile iOS App

Buttons created in Adobe Acrobat Pro are not working in the Adobe Acrobat Mobile iOS App (not tested on Android). The hyperlinks do work. Everything works fine on desktop, in the Apple Books and Google Drive apps on Apple phones. (Buttons not working when opening file in Dropbox.)

I am working from a scanned PDF (so not initially created in InDesign). I created all the interactive functions within Adobe Acrobat Pro. I have seen on the forums other people having issues with the mobile app. Is that still a problem? Thanks.
