I had same when I turned on the bird after the FW update. I had left the GP on during the firmware update.... Try this order for turning everything on...worked for me.
Bird, pause to let it boot fully - to White/Red LEDs
turn on Controller, continue to GP even though controller is booting up
GP, should have charging light on at this point. Hit the ON button and should boot up.
Start App and connect to Solo WIFI
You should have the controller's screen indicate that it recognized the Gimbal and then will say Solo app connected.... if done in the above order. If not, I would insure the GP is properly installed and try again with above. Main thing, in my opinion, is to not start the GP prior to the bird being fully booted.
Good luck!
