Not sure how often his xml files update, or what timezone @matthuisman is in (NZDT, UTC+13 ?), but the timestamps here Index of /SamsungTVPlus/ have been stuck at 11-Feb-2023 15:16
Looks like the xml file updates hourly
Appears the timezone is NZDT, UTC+13
File date/time just updated to 11-Feb-2023 17:20
But the program schedule inside the file didn't update
So there is no current schedule in the file
