No guide channel info, no recordings

This morning I find that in both regular channels app and beta version, when I went to the guide there was only channel call sign and channel number shown for all programming details, ie every channel, each half hour slot only showed call sign and channel number rather than program title, etc. Therefore no recordings I had scheduled were recording

I rebooted appletv, updated firmware on each HDHomeRun device, etc

Suggestions ?

I went into my DVR server, opened the channels app, found the guide refresh options and told it to refresh - didn’t seem to do anything but then 10-15 minutes later I went back in and all is back to normal now

I had that issue yesterday with ATV and only on OTA channels. Updated to 5/25 yesterday and this morning they're back to showing correctly
