Tunarr is pissing me off.

I'm running Tunarr as part of my *arr stack, along with Plex. When I first setup Tunarr, I couldn't get it to connect to Plex; whatever, I just added all my media as local libraries. I'm still OK with that setup, but Tunarr just seems to "silently fail" on different occasions. For example I was trying to make a channel for my kid that consisted of about 5 or 6 shows, some of which ran for like 30 years so there's a lot of episodes. No matter what I do, the channel only seems to add certain shows and just ignores others. And I don't think it's the length that's the problem, as I have another channel that has even more content. The point of this post is, what's a better alternative? I checked out Programarr but I'm not looking for something to build lineups for me; I know what I want, I just want it to actually get added to the channel or tell me why it can't be added.
