@Bluemoon1 looks like you are the same as me. Those version numbers indicate that you are part of the YouView trial of a new interface (Feedback group should say yvurbtboxproux). You should have had an email from the YouView Research team explaining things. I emailed the YouView Research team to ask about the other software versions and this is what they said:
1. Was the delay in receiving the 4.0.246/0.6.124 and Visual Guide on demand updates because I was scheduled to be in the trial?
There was a delay for all trialists just down to the way the way the software was deployed.
2. What happens after the trial is finished? Will the updates I am missing be downloaded to my Pro BoX?
You’ll get the missing software after the trial.
