I like that you can easily add in new apps as they are available without having too many steps or changes required - great! It's also very flexible when adding custom rules/approvals (as well). Sometimes there will be an error but nothing major at this point though so we haven't been able push back yet since everything works fine otherwise just go through your normal process if something pops up here & then make sure its not anything serious before pushing forward again :) Great tool overall especially considering their support staff has helped us figure out any issues quickly which helps reduce errors along the way!! Not much other than some minor bugs once now where no big problems have arisen because our system admins were quick enough to get things resolved ASAP.
