Live TV Guide not fully updating

I’ve been trying for sometime now to get Plex to investigate a problem that exists with EPG guide data not fully populating during the nightly updates.

So far, I’ve not heard anything from Plex on the issue, even though I believe I’ve followed all the steps that would be needed to get a response (Hardware: Shield TV Pro, PMS version: 1.14.1.5490, uploaded logs and images.)

I’m at a loss as to how to get support for ongoing problems with the EPG. Am I missing something in this process or is it broken?
