@Emil I managed to check the battery and it was still at 85%+

I have disconnected and reconnected from the system and hopefully that will resolve it.

@Emil Thanks for explanation.
Works now...
I also managed to figure out what JSON structure is going for MDM under point 3.
Basically I export pairings from dev hub and if we use those buttons on managed hub I just paste "buttons pairings" json in to the field.

Figured it out. Just needed to use an international format for the phone number (put a 1 at the front)
