Should the Greatest Book Video Series be showing up in L4? I don't seem to find it.
No, according to http://www.logos.com/4/missingfeatures Video resources are coming during the second quarter of this year.
Videos are a part of the upcoming features of Logos4... So eventually if you had the license for the series, it will be added (I have it too, so I'm patiently waiting.) According to the Logos website on missing features, it's supposed to be sometime in 2nd or 3rd quarter if I remember correctly
