why i cant scroll down/up the channel?
if you use Unifi Plus Box, you can scroll up and down when you press big button on ur remote UPB.
if you still can't scroll up or down, go to setting and clear chache and clear data. after that, you need to restart ur UPB. after restart, please sign in ur id and password unifi tv.
please update ur unifi plus box to Android TV version 10. this version very smooth and no error if you play any application on unifi plus box.
