GCM upstream messages are triggered twice

Question

I use gcm for instant messaging. I have the problem that upstream messages coming from anyone's device are sent twice with a delay. That means the first message is sent immediately and the second same one is sent some minutes or hours later.

Can anyone help, please?

This question seems similar to this [SO thread](http://stackoverflow.com/questions/15102055/gcm-duplicated-messages). — ReyAnthonyRenacia, Jul 15 '16 at 07:24
Could it be an issue with the ACK that you are returning to CCS? — Arthur Thompson, Jul 15 '16 at 16:33

Solved the problem. I just catch all duplicates according to my business logic.
