The Sky Stream box was updated with the TV Input app in error and is being/has been removed. It should only be available on Sky Glass.
According to a comment from Sky on the
https://www.ispreview.co.uk/index.ph...-channels.html article
'Sky has confirmed to ISPreview that the Digital Terrestrial TV (DTT) function was briefly turned on for Sky Stream in error, but was quickly rectified and turned off again. This is partly related to the fact that Sky Glass already has the same feature and the two platforms share the same underlying Entertainment OS software platform.'

'As some of you may have noticed, last week we enabled the DTT-App on Sky Glass as one of the default available apps, meaning it is now accessible without the need to disconnect your internet. However, as part of that update, the app catalog for Sky Stream was inadvertently updated with the same configuration, causing the app to become briefly available on Sky Stream. This was unintentional and has since been disabled. '
