My tello arrived 2 days ago, read the directions, synced it up, made my 1st flight ever and it was successful, I'm happy to say! After I turned it off and came back to it later, I turned everything on- the wifi signal showed on my phone-acted like it was connecting but the app never picked it up and the lights on tello stayed blinking. Tried multiple times to get it to work and had to delete the app from my phone and reinstall ...and I've had to do this for 2 days now. Is there something im missing? I have a Samsung S9. Thanks for any help in advance!
