It works as long as you don't reset the PVR causing it to reassign new channel ID's. You must have a setting selected which resets PVR Channels on boot.

Oh, it might be the case. But where do I find this option? PVR IPTV Simple Client has options like m3u location, user-agent, EPG settings and channel logos settings. I don't see any option related to channel ID's that confuse AutoWidget.

I don't know if there is an option or setting, because it works for me. The only time it fails is if I select Clear Data in PVR Settings, which causes the channel ID's to reset.

I never touched Clear data in PVR settings. I just tried again whole process, resetted Kodi, installed latest Arctic Zephyr 2, installed latest AutoWidget, configured PVR Add-on with my m3u file, made Home item with submenu and added 15 widgets to submenu (15 channels). Tried does it work, it does, closed and opened Kodi, it doesn't work anymore.

Perhaps it's related to Arctic Zephyr 2 skin but if remember right on 1st page is marked as fully compatible. This is something author of AutoWidget should really look into asap.

I managed to reproduce this on 2 Android 9 devices and on Windows 10 as well with Kodi from Kodi website (not the one from MS Store).

I never said this but earlier it worked fine, I will now test this with previous Kodi version and AutoWidget version.
