Regarding APN tokens

We're currently unable to send pushes to certain devices.

The tokens are being received by the app APNs, but when we send the push, we get an error stating "device token is inactive for the specified topic."

It looks like expired tokens are being used.



As stated in the documentation, we're retrieving an APN token with every launch of the app.

However, on the devices where this error occurs, the same expired token gets returned even when requesting a new one.

Are there any reports of a similar issue? Any advice on how to fix this?

Similar situation here, we are using HTTP2, the response is 410(Unregistered) with a timestamp.

Same that we retrieve APN token at every app launch, and the "expired" token is returned.


Findings:

1) the token can still be pushed successfully using the old protocol.

2) so far our affected device are all iOS 10.0.x, but not all users with 10.0.x are affected.

Same issue here, but retrying to push with the same token later and the notifications is properly delivered.

We are currently experiencing similar issues. Did you ever gain any additional insight into what was going on ?

Same issue here. Any update?

I also have same issue? How to resolve this issue anybody?

I also have been experiencing the same issue. We also are using the HTTP/2 protocol, and both debug builds installed through XCode and release builds installed through TestFlight have had this issue.
