That is the smarters apk version.
Last night I was setting up an old MiiBox for a friend, and I ended up installing the other XCIPTV version app. And EPG worked perfectly. It was this one: h t t p://apk.wickediptv.xyz/
Did you try clearing the CACHE or forcing the APP to reload the EPG ?
EDIT: I completely forgot I had the "newapk" version on my phone (pixel 7 - Android 15), and I just tried it, and it loaded EPG no problem.
