Thank you for your help, it's true that it's very strange to use two notification services at once, and I've tried using the HTTP/2 header "apns-collapse-id" this works and combines the notifications into 1 when the iPhone is locked, while when the iPhone is open (unlocked) the notification banner still two. and I didn't find any solution for this except sending the exact same notification only 1 time.
Additionally, why use two notification services ? is as a backup, if the first one is not received by the user, then the user can receive the second one and vice versa
