Channel Four channels frequency change on satellite (Sky and Freesat)

A number of Channel Four group of channels have changed satellite frequencies today.

The change has affected the following Channel Four group of channels:
E4+1
E4 Ireland
Channel 4+1
More 4
Channel 4 Ireland
Film4+1
Film4 Ireland

These channels used to be on frequency 10.729 V

They can now be found on frequency 10.936 V

I have no idea why the change.

Users of Sky and Freesat boxes will have automatically updated to the new frequencies.

Users of other satellite receivers will have to manually update
