I have two DVR servers with a TVE source that didn't get their daily morning guide update.
They were both running v2021.09.10.1817 before I updated them to v2021.09.10.2301 this morning.
Don't know if it helps, but here's diagnostics from both of them.

Another server with an HDHR source did get the guide update this morning.
It was running v2021.09.09.0142 and I updated to v2021.09.10.2301 after the guide updated.
