Since the latest update to the BT TV app it appears to be incompatible with the T1000.
Message I get when trying to set up a recording.
"Sorry - there is a problem.
This feature is no longer supported on your current TV box
To use this feature you will need to upgrade to a newer box. For TV box and
package options, please visit bt.com/tv (GY184)"
😞
Don't know what GY184 is coz it's not listed amongst the error codes.
I think I might be speaking to BT to get a replacement box.
That is a legacy 1st Generation Youview/BT Box so it is likely that it was using the old infrastructure for sending remote record requests and servers which Youview have ceased. So that would affect the 1st Generation Youview boxes and also those using Youview own app (now withdrawn) on any box.
