Very strange indeed.
What about “Saturday 11:29PM”, does that one work?
No.
I wonder if the timezone on your QNAP is incorrect?
The time was incorrect on the QNAP and is now repaired. Do I need to refresh Channels somehow?
Don’t believe so, it should notice the time is different. If not, try stopping and starting the service.
That did not fix it.
Perhaps you need to reboot the NAS? Not really sure…
