I really do apologise if this is not the appropriate place to ask however, the problem is that severe now that it actually has the potential to cost my business money, so I really need to find a solution.
For at least the past 3 years, I've been experiencing delayed GCM notifications. Basically, any app that relies on GCM to deliver push notifications will be delayed.
My partner has the same phone as me, uses the same carrier, same WIFI networks but all of her notifications are virtually instant. Mine can vary from 2 minutes to more than 20 in some cases. Regardless of what device I log into and what networks I'm using, notifications are 'ALWAYS' delayed for me.
If this is in fact the case, then how do I confirm what my heartbeat intervals are and if they are incorrect, how do I correct them?
Your help would be greatly appreciated.
Thank you!
Ray.
PS: I'm using a Samsung Galaxy Note 8 at present. Previously a Nexus 6 - which is when the problem was first noticed.
