Apparently the same bug that caused the M3U file deletes, is causing the channels disappearing too.
We are working on it.
Please be patient.
UPDATE:
Most channels (tvg-ids) are back.
USA and Canada are still generating, but should be available soon.
If you import an m3u file or a backup, do not just assume that everything is fine.
Go into the editor and set your groups and channels to "GET EPG" if they are not and add the tvg-ids to your channels.
UPDATE2:
US and Canada channels are also back.
This issue is considered being fixed now.
Thank you for your patience.
