i had this problem 21dec but it went away the day after so only conclusion i came upp with is that your isp is having major loads on the port iptv is streaming
im connecting through mag portal so i dont have to mess around with epg files , on my side connecting through mag portal i get all the epg (well im missing like on 15 channels) but no big deal for me
well that will work if you using m3u but some of us is using magportal or user/pw and in that case you are getting epg from epg servers which are unstable atm
there seems to be an issue with the spaces between words on all epg or atleast sweden/uk/us for example it says topgear when it should say top gear (with spaces between top and gear).
first i thought it was my z7+ but i installed xciptv on my sony android tv and its the same thing
