login to your dashboard,
left side: manage lines,
right side: OPT (3x dot),
click on BOUQUET LIST and activate those countries you want to see.
you can use the epg per country, this should be also available in your dashboard, but if you want one epg link for all countries:
simply replace OWN.DNS with your m3u links dns and replace the XXXXX with your m3u username and password.
if you need help with it, feel free to send a
PM to me.
