Logitech Combo Touch not detected on reattach; onscreen keyboard appears

Fix for detecting Logitech Combo Touch Keyboard after detaching the keyboard. On reattach while typing input is detected Apple’s own onscreen keyboard pops up also. General fixes circulated are to go to Accessibility and toggle Keyboard off on, etc or to restart the iPad. A simpler fix is to close the keyboard cover on the screen and re open this. Found this by accident and it works. Only issue is I have put the settings to lock the screen on closing the cover so have to unlock it.
