I believe AppRF reports are only coming in AMP 8.0.
Looking at AMP 7.7.10, that canned report is not there. You can view AppRF data on AMP 7.7.10 but you cannot report on it.
Charlie, what you need is AOS 6.4 and AMP 8.0 (which is still in beta) if you want to run reports.
AOS 6.4 on 7200 series controllers will give you AppRF 2.0 vs 1.0 on AOS 6.3 which let you see which video sites they are going to.
