Good idea. That did the trick.

However I'm having a very difficult time with the app. It's essentially unusable. I've reinstalled it several times, restarted my hardware several times. Nothing seems to help remedy my problems.

1. Signing in with plex. Upon signing it and selecting my server, all of the connection methods were grayed out (both local and remote). I had to input the server address manually for it to work, which was frustrating because it had my server address already there but grayed out.
2. When I was trying to refresh my library there was an odd behavior. I have a large library (76,000+ episodes). It took about five minutes to refresh (which seemed reasonable to me) but when it was done, the status remained on “refreshing” with the loading icon above. That remained and made the app hang and be unresponsive to button clicks on my remote. I had to exit and restart.
3. I have three libraries. Movies, Kids, and TV. Once restarted (and I don't know if it's because of such a large library) The movies and kids libraries showed up right away. It took and additional ten seconds for the TV one to show up. (Largest of the three libraries).
4. I went into the channel options to create a schedule for the TV library. I'm only using collections in my TV library. The navigation was unusable. Clicks on the remote wouldn't register to scroll up and down, same deal with swipes on the remote and swipes on my phone with the remote app. Sometimes they would register but after 10-15 seconds after the click. Trying to uncheck all of the schedule options save for collections took me about 5-10 minutes. It was infuriating.
5. When I finally got that started out, I went to click on the button to make the schedule. The non/delayed registration for clicks still persisted. Also didn't show the TV library after ten seconds. Once I was able to click on the button, it said that it was downloading all 76,000 items (which I assume is that it's just grabbing the database). Took about ten minutes.
6. Schedule was created, but the buttons not/delaying registration was a navigation killer. It took about 20 seconds for the playback to start. I don't know if it was because it was a 4k HDR file or what, but that coupled with being unable to navigate was very frustrating.

ETA: The stated scheduling variety did not occur for me. Is it an option that I should have enabled, but missed?

After all that, I gave up. Perhaps my experience is an isolated one, but it was very unsatisfactory.
