Experiencing 403s (InvalidProviderToken) [https://api.push.apple.com/3/device/<DeviceToken>] due to invalid or unverifiable provider tokens. We have noticed that after retrying the request inline, the notification is delivered successfully without any changes to the request even with same authorization token.
Someone please guide or suggest why it is happening as the JWT token which is generated is correct because we are caching the jwt token and using the same token to send out the subsequent request which is kind of successfull.
Sending the notification for multiple team Ids under the same application.
