I recently switched providers and almost all items in the EPG have overlapping text. A common issue I know, but I’m hoping you can help diagnose if there’s anything wrong with the EPG info itself and whether I can provide any feedback to the provider. I’ve uploaded the EPG file here: https://1drv.ms/u/s!AuHmyzi_gaJUsHknZenaa488J1Wy?e=PLDXIo
1) EPG overlapping issue is well known and the reason is buggy EPG source. You can find more related info on this forum.
2) You should contact your IPTV provider to ask if their server supports “filterCategory” URL parameter.
You can also use Settings->Advanced->Groups management mode to hide some groups. Use “Hide group” item in channels list context menu in this mode.
