Maybe try the latest version of smaters
Have you tried clearing the cache also saving EPG locally n loading it that way?
check your modem routers time and date .. restart the modem should fix all devices as they get time and date from that.
also go into android settings and look at android time and what country it's set to etc.
are you using the latest version of iptv smarters ?
How to get latest version on Apple TV ?
UPDATE: Resolved. Thank you to those who responded with suggestions--even the ones I already mentioned trying. You are all whst is great about this community. I posted elsewhere in this thread that changing your timezone, turning off VPN, and restarting the firestick or firetv will fix the issue.
I am probably going to get downvoted further for this, but I don't care because it is just internet points. I don't understand the reddit community as a whole. I searched in this community for an answer to this question prior to posting my question because I figured it had to be a problem that somebody else had since it has happened to me on a couple of occasions. I thought one of the purposes of this community was to resolve issues people may be having with IPTV. Thanks to a suggestion by another user here, I figured it was a firestick issue--specifically firestick 4k issue when I originally thought. This problem will most likely get asked again in here as many people are using firetv 4k for their IPTV and it does mess up the EPG. Despite this post showing a resolution, it has been downvoted as if it has no significance to this forum. This is counterproductive to the community and I don't know what possesses so many redditors to arbitrarily downvote a helpful post.
