yesterday i flew and evertthing was fine. today i get ready but message says (rc not connected to mobil) i double checked all connections, battery full charge

I had a similar issue last night. Quick restart of my phone and it connected up no problem

Hello there. I am sorry for the trouble this has caused and thank you for reaching out. Have you tried to a different cable if you have an extra to connect the RC and the smartphone and kindly please try to restart your mobile device to see if the issue will still persist? In addition may we know what is the model of the mobile device that you are using please? Thank you.
