Good morning,

We can use two diffrente cellphones with the Mavic Pro remote control?
I try to use my Iphone 5s, but the camera did not stream image from the drone to my cellphone. This cellphone was linked to other drone at first, but three days later we bought other drone and linked it to my cellphone.
While using other iphone 5s cellphone and everything is well, the only issue is that is my cellphone to work.

We can link different Drones to only one cellphone?

You should be able to use any phone that works with any drone and any drones with one phone as well.  Obviously not simultaneously.  If they are attached to a different account you may have to log out and in on the app I am unaware as all my drones are on one account.  But I have no issues using my one ipad with multiple drones.

Yes, you can use two different cell phone with the Mavic pro, but not the same time. May I know what is the APP version on your iPhone 5s? Have you tried to reinstall the APP?
