Help needed to connect XDJ1000 to Rekordbox for iPad

Equipment: 2x Pioneer XDJ-1000
Firmware: 1.13
iOS device: iPad Pro running iPadOS 17.0.1
Rekordbox: v4.0.4.11

Dear community,

I tried two scenarios:
Scenario 1: WiFi
I connected my XDJ's to my WiFi router and wirelessly connected using Rekordbox running on my iPad.

Scenario 2: Network switch
I connected my XDJ's to a network switch and connected using Rekordbox running on my iPad using a network adapter connected to the same network switch.

For both I get the current behavior:
1. I tap 'Connect to CDJ/XDJ/DJM' on my iPad
2. I get a prompt saying 'Connected to CDJ/XDJ/DJM'
3. I tap 'Rekordbox' on the XDJ
4. I select 'iPad'
5. I tap the selector to allow the connection 

However, nothing appears. No collection, no playlists, nothing.

Also on my iPad the prompt as displayed in the first picture stays.
And if I tap master or sync on my XDJ, it shows like that on my iPad.

I also tried using my iPhone to do the same but I get the same behavior.

Please note that if I use my iMac to connect using pro-link it works as expected and shows my entire collection and playlists

Any help is very much appreciated
