Flight modes are gone from the screen menu i.e Follow me, Way points, etc

The menu with the flight modes are gone. and I can’t figure out how to bring back onto the screen again.
Thanks in advance.

Turn Off then On again your smart device (phone) and try again, or reinstall Litchi.

I did unisntall and install again the app, with no success. Maybe if I try to delete all the stored data, I’ll succeed.
Thanks for your advice.

Problem solved!
Deleted all the files and reinstall the app.
Thanks to everyone
