Kryptview channels

Hi,
I am missing a few channels from my KV (e.g., Racing UK, Gold and a few music channels)
In order to get them back on will I have to re scan my box again or will the come back on automatically when the box is on stand by?
Also does anybody know if you get the PPV channels on KV? Like the boxing when it’s on?
Thanks

There is still maintence on KV some channels are still going off and on.
Don't bother scanning as the channels are not there at the moment.
Leaving the box on stand-by lets it update.
Have not watched PPV on KV but am told it can be viewed
