Apple PassKit, webservice invoked hundres of times

I’m using Spring Boot 2.2, Spring Data REST, hibernate in my REST application. I’m trying to manage Apple loyalty cards.
I’m using jpasskit to generate the pass (.pkpass bundle) and it works like a charm. Because I want to manage updates of the pass, I set the webServiceUrl.

I implemented all endpoints described in Apple’s documentation but I’m facing two big issues:

  1. as soon I install the pass in my phone, Apple start to send me a LOT of register requests (just for one phone). Every request has a different deviceLibraryIdentifier (I know it’s normal, it’s not guaranteed that the phone sends the same identifier every time). With “a lot” I mean hundreds in few minutes. I reply with HTTP 201 because every request has a different deviceLibraryIdentifier
  2. When Apple call the endpoint GET request to webServiceURL/version/devices/deviceLibraryIdentifier/registrations/passTypeIdentifier?passesUpdatedSince=tag the passesUpdatedSince is always empty, even if I set it when I reply. I also checked the Apple server example and what I do it seems correct to me

These are my apache logs where you can see POST requests from Apple and the result code HTTP
201. This is just a small extract from logs:

Any idea of what I could check to fix these problems? I’m testing all with an iphone 6s with iOS 13.3.1
