WOOHOOO! Problem solved. Many thanks @OzoneVibe
Uninstalled version 1.4.2 of the DJI Fly App. Rolled the it back to 1.3.0 and it worked fine. Uninstalled that and rolled back to 1.4.0 and that works fine too.
Conclusion…Latest update of the Go Fly app (1.4.2) doesn’t work well with the Huawei M5 Lite, or it doesn’t with neither mine or the girlfriends.
