Update: My replacement MA2 arrived last night from Apple, no issues this time, it activated right away and so far its behaving great! FWIW, I updated the firmware, AFTER I activated this time.
No! The first time I updated first then tried to activate and got the activation error, so this time I activated and then updated. I'm not sure if they are related, but circumstantial evidence is starting to add up after reading some of these other posts.Did you update firmware before the activation?
Yep, that’s standard when the drone gets a FW update, each battery normally requires a matching FW update as wellMine arrived today from Amazon. It activated immediately with no problems, then upgraded the firmware. I got the Fly More Combo and after I did a quick initial flight I swapped to another battery that had been on the charger and discovered that you have to update the firmware for each of the batteries. I'm a newbie and I was surprised by this.
