Install iptv apps on sony android


Ok so i was able to install my iptv app on my sony android using puffin browser a lomg time ago. Installed cyberflix etc by same proccess.

Now my iptv app has stopped working, i need to installl a new version.

Puffin browser no longer opens and atock internet browser wont open my app. I definitely have allowed unknown apps ticked.

Any help would be great
