A Little Pillow Company review for Microsoft Channel

I don't know how other Shopify stores have managed to get this app to work (according the recent reviews) but for the life of me (and MS support and Shopify support) it will not work. I am so disappointed too. I keep getting a message saying "cannot validate your credentials at this time, etc." I've been uninstalling and (attempting) reinstalling multiple times over the past week and still nothing. Sure wish Someone out there would figure out what's going on :(
