We have worked on resolving the problem for days.
I wrote my codes and tested well in my working environment, however, with the same codes running on the production environment (with the server put in IDC), it worked correctly with just few notifications, the problem happened when about 15 notifications to be sent, and about half of them are with invalid device token. Looks like the failed notifications will block the following notification with valid device tokens. The weird thing is that with the same code, same notification set, running on my working environment will work perfectly without any loss.
Can anyone kindly suggest us or any clues?
Thanks a lot!!
