Blank line showing for random channel on guide grid

See image. (ch 9.1)

This happens intermitently for random channels. It eventually self-corrects later after undetermined time lapse.

Is there a fix/work-around to stop this from happening?

Running DVR Server v2023.08.18.2205 on Win10 PC. Running client on Fire TV (v7.6.5.2).

I have noticed the same thing on my FireTV. One of the first 5 seemiingly random channels listed goes blank in the guide if I move right a couple of hours. I don't use the guide too much never reported it. It seems to fail consistently after several minutes of watching live TV.

Thx for reporting and confirming it's not just me. We now know there at least two users with this problem.

I have noticed a few blank spots but they always in the far left closest to the channel number block. Is for the current airing program that is missing.

Other times, the guide data on the client device is not updated, cause the app was dormant, not closed out. Closeting it out, force close or whatever, then reopen, loads the guide. Same with the Recordings screen. (Apple TV though)

Yes, I also see another bug in the guide. If I hold down the move right key continually going to the future then the guide eventually will lock up on me before it reaches the end of the guide time. When it stops nothing is showing to be selected. The developers are not that fond of FireTV s/w, it is apparently buggy, so I try to live with some of the bugs.

I understand and don't disagree with what you're saying but it seems crazy that Fire TV is "buggy" after all these years. Surely Amazon has the resources to diagnose and fix bugs!

These bugs have been around forever.... maybe sometime they will look at them and fix them.
Ghost Channels is another.

I have only noticed bugs using Channels DVR, at any rate the Channels developers have a problem with the FireTV OS. They support it plenty fine for me. I like the Firestick 4k Max, it has been a great device for me and my family. I will give up Channels DVR before I would quit using the FireTV.

This is not only a Fire thing, it happens on my 2019 Shield Pro client using a Win10 server.

[edit] Actually, I usually stop before it locks and see the times are way off in relation to the shows.

What do you mean by "dormant"? Idle? In any case, if the app is running, it should receive updates via the server (where the guide is managed - see 'Guide Database' in server Settings). ATM, my server settings 'Guide Database' Maintenance shows "Last refreshed 21 hours ago". No idea what the guide update frequency is - but's it's over 21 hours for sure. Not good - that's too long.

Almost a week since this thread began. Any progress on a fix/work-around to prevent the blank-line problem? Or, at least a supposition re the cause? Thx.

Dormant, meaning is in background/suspended. I am not sure what Apple call it.
U can see the app in the App switcher. But am using other apps. It is not fully closed unless use close the app (force quite or app switcher the litte X on Andorid TV)
