I have had my drone for 5 hours already and can't fly.  Remote and GO app doesn't
connect.  Suggestions before I refund?

The DJI Assistant isn't connecting either.  

Hello there. I am sorry for the trouble this has caused and thank you for reaching out. Have you tried using a different recommended mobile device to see if the issue will still persist? Upon checking the said mobile devices ( Pixel 5 ) that your are trying to use on your DJI Air 2S and with the DJI Fly application. I am sorry to say that the said mobile devices are not recommended for the said drone and with the said application. We would suggest using a recommended mobile device for the DJI Air 2S and with the DJI Fly application for compatibility and reliability purposes. There is a possibility that the Pixel 5 will be able to work on the DJI Air 2S and with the DJI Fly application. But however, since it's not yet optimized with the said drone and with the said application we cannot guaranteed if it will work all the time and if it will be able to run all the functions of the DJI Fly application while using it on the DJI FPV. For reference I will post a link where in you can check the recommended mobile devices for the DJI Air 2S ( https://www.dji.com/air-2s/downloads ). Thank you.
