Apple TV stream ends after program when channel picked

I’ve seen several similar comments; but they’ve all been closed/locked so I can’t add to them.

Recordings are fine. Live streaming individual programs is fine. When I choose a channel (not a program) I expect that the next program will continue automatically. It does not. A few minutes after the next program starts, the stream sometimes seems to loop and sometimes simply stops.

What is the trick to avoid this?

Choose the channel number, not the current program on the channel, to keep the Tablo playing the content in the channel.
