After app transfer Push notifications were not sent to old users

We have changed the owner of our ios app (app transfer)
Since (I don’t know if it’s related) old users in the system do not receive notifications (APNSDevice)
I thought maybe we should manually update their registrationId
Can you please advise how to find the the cause of the problem
Or is it possible to manually update the registrationId?

We are using phonegap-plugin-push

    pushObject.on('registration').subscribe((data: any) => {
      console.log('device token -> ' + data.registrationId);
      this.app.setRegistrationId(data.registrationId);
    });
