Had to update my second battery upon switching to it. Update stopped at 98%.The change log told me to restart the drone and RC if there was any issues. Didn't feel comfortable doing so.I Instead disconnected the wifi from my phone. After I reconnected it said update was successful. Should I be concerned ?

Restart the drone and APP, then check the Battery info on the APP, see if everything is normal.

Seems all normal to me.

Mine took a while (2 - 3min) to get over the 98% hump. Just let it go, it should work.

Yep both mine also took a good few minutes to progress from the 98% mark, I just left it any eventually it completed.
