Could anyone help with app/ drone bound to another Email...
I purchased DJI Mini2 off of someone, when checking in the app says bound to, D--------@ outlook.com this was the seller. I don't have contact details for this person.
In short how can I get this bound to myself?

You'll be unable to unbind that yourself, if possible try and ask the person you bought it off to unbind their account via their DJI Fly app. Otherwise it's impossible to remove yourself

Thanks for your reply. Have since discovered that, but I don’t have contact details for the seller anymore.

Is the email in your post displayed the same way in the app? (Not showing all characters)
If you see the complete email you might start there. You may have to contact DJI to request the unbinding by the previous owner.
