Since the above command works just fine for me: what exactly did you try?
Especially: where was your myapp.desktop file located when you executed
xdg-desktop-menu?
Was there already a copy of myapp.desktop in some of the places relevant
for the menu system, for example in
~/.local/share/applications
/usr/share/applications
/usr/local/share/applications
?
Was a myapp.desktop created in /usr/local/share/applications?

Might be some kind of caching, which is causing this.
Does issuing
sudo xdg-desktop-menu forceupdate
after copying the .desktop file make a difference?
