HI! I'm a customer from Thailand.
Currently , I'm using Samsung galaxy s6 edge and just update my android version to 6.0.1 instead of 5.1.1.
Since I've update my device , GCM has always stopped with message "Unfortunately , Connect has stopped" when I try to open the app.
Try to connect you via play store & e-mail to product support.
They suggest me to 1. Open location permission and 2. Clear cache on my device setting.
I've follow their suggestion but it's still same.
What should I do ?? Anyone found this problem like me ??
Please help...
