When I try to redistribute all failed content, it looks like it is only working on one package at a time. It lists all failed content in the confirmation window. 1 package will redistribute successfully but it does not continue to other failed packages.
Sorry for the ridiculous delay here. I want to say we fixed that in the 4.0 release in October. Give that a shot and if that isn’t the case go ahead and make a support case: https://www.recastsoftware.com/support
