This certainly isn't what we like to hear, Sunny. At this time, we recommend uninstalling and reinstalling your app as an initial troubleshooting step. If this doesn't work, please send our team an email at socialmedia@gm.com with "ATTN: myGMC/Sunny Sun" in the subject line so we can look into things here on our end. ~ Steve
