Hi Troy , I’ve loaded your latest version of IPTV Smarters on 2 new 4K Firesticks today.I’ve loaded the relevant login details on both devices and as soon as I go to the setting icon the apps crash so making it impossible to alter stream format, player setting and player selection. I managed to find an older version of the app and all is as it should be being able to alter the settings. Can you help please? Regards, Richard
