Not sure why this worked for me but I thought I would share it. On both my Plex servers I was able to get he EPG data loaded 100% by doing the following:
- Navigate to Settings -> Live TV and DVR. Click “Refresh guide”
- Navigate to Settings -> Troubleshooting. Click “Optimize Database” followed by “Clean Bundles”.
- Repeat steps above. Each time you do the process the EPG refresh gets a little further.
