I have also posted this on Github, but copying here in case others are seeing the same thing:
I have had an issue recently with a dual appearance of a single channel in my IPTV playlist appearing twice in the EPG, on Kodi v20 only - see post #641 in this thread. @
matthuisman provided an update yesterday for IPTV Merge to v0.24.8
I think that this update has had an unintended consequence - at least for me:
On my Kodi installations I also use the TV-Headend plugin to add British free satellite channels. These appear on the EPG as genres "Freesat" and "Regional" and sit neatly at the end of the top row, after all of the IPTV genres listed in my playlist. The satellite channels get their EPG data "over-the-air".
Since Merge's upgrade yesterday, The satellite channels have not been updating EPG data, but the IPTV channels are still fine. I have tried clearing the Guide data in both locations in Kodi. Although it usually takes a few minutes for the EPG data to repopulate, (sometimes up to 10 minutes for all of the satellite channels), I still have no EPG data for the satellite channels after 2 hours. The satellite channels can still be viewed, just no EPG.
Again, this issue only affects my Firestick with the Kodi v20 installation, both devices using Kodi v19 are still working fine, even though they have also upgraded to Merge v0.24.8
Am I correct in linking this to the Merge update - or is it just a co-incidence?
If I disable IPTV Merge and IPTV Simple Client, the satellite channels EPG populates correctly.
Whereas the previous issue that the update solved was annoying, no EPG data for any of my satellite channels is far more problematic.
If the "solution" is to revert to Kodi v19.5 on this Firestick, then I'm happy to do that - I wanted to test v20 again as I'm concerned about my installations becoming out of date and unsupported in the future?
