Connect Pioneer DDJ-RB to iPad

Hi,

I recently switched from a Pioneer DDJ-ERGO to a Pioneer DDJ-RB controller. I managed to connect my DDJ-ERGO to my iPad running Algoriddim Djay2 (after pressing button combo: https://forums.pioneerdj.com/hc/en-us/community/posts/203081489--CLOSED-DDJ-ERGO-won-t-work-with-iPad-Air).

However, I am now trying to connect my DDJ-RB to that same iPad, but don't get it working. It is not showing up as detected Midi controller.

Can anyone advise? Do I miss a step?
