I created a presentation for windows and everything works perfectly while the android version if I click on a window containing a link to open a web page does not open it in any way.
I had the same problem.
For me it worked on android only when I inserted the link containing “https:” or " http" at the beginning of the link.
exaple:
www.google.com >>> Does NOT work.
https://www.google.com >>> Works perfectly!
