Since the update from coins to ink, now seeing "CHARTBOOST_no_host_activity" error/message when the "Watch Video" link is tapped on Android phone, then link is greyed out. On Android tablet, link becomes greyed out after tapping, but no message appears. Appears there might be a problem with part of the update after the change. Am in US, so that should not be part of the problem.This problem has been happening for the past two days; have restarted both devices, no change, so there might be a problem on the back end. That, or there are many, many people using the "Watch Video" so there are no videos available, but since I've tried at many different times and am continually receiving the same message, it 'feels' more like a problem either with the app's connection to the CHARTBOOST system.
