0 Check-in Windows Application 3 Austin Spooner posted 8 Years Ago I am having some difficulities with the check-in Windows Application. Currently when I enter the url into the Windows Application it just sits on a white blank screen and does not progress. When I enter the same URL into a web browser or the iPad application it works fine. Does any one have any tips for troubleshooting the issue with the Windows client? I have the same results on 2 different versions of Rock as well.
