Button links not working in mobile acrobat app in new release update

I could get this to work a couple months ago, if I actually downloaded the file produced in 

Acrobat Pro, then opened in Acrobat app. (It didnt work if I just tried opening it from internet).

With the new release, this does now NOT work.  In your own product!

Works fine on another PDF app on IOS.

We are all using electronic documents and working from home using ipads etc.  I am amazed this feature no longer works. 😞
