Changing channel from Get TV to Antenna TV

On January 1 2015 in Birmingham Alabama 21.2 which is Get TV will be changing to Antenna TV will the guide update to the new channel or do I need to contact Tablo ot inform them of the change?

@John_Welborn_Jr - It SHOULD just update but please send a note to Tablo Support so we can give our guide provider a reminder that this is happening:

Ok it did update but they moved get tv to 21.4 and it’s not showing any thing on the guide it is blank. Before when it was on 21.2 it showed what was coming on.
