One of the issues we have run into is in requiring SSRS to use SSL otherwise it's just a nice internal site and Mobile Reports are only visible from our network wifi or VPN as we are not in the mood to pass AD credentials in the clear.

Attempts to change "SecureConnectionLevel" and <UrlRoot> work great for reports with SSRS reports however data sets used by mobile are unable to be reached by the mobile reports. Almost seems like Mobile is not able to communicate to the datasets using SSL.

Setting SecureConnectionLevel = 0 seems to be the only method for these to work.
