Dev Mode on secondary user profile after v74

Hope I ask this question in the right forum - if not my apologies in advance.

With v74 we got the option to pair secondary user profiles on the headset to their respective Horizons app. It works - I can confirm that. However the dev mode toggle seems to be greyed out in the app of the secondary profile (works flawless on the owner profile) eventhough the account is verified as dev.

My questions: Is it not possible to have multiple dev mode profiles on the headset? What could be the reason the toggled is greyed out and how can I fix this to allow dev mode on both profiles on my headset.
