AMP no menu

Hello

I have a little problem, I have configured the AMP module but I can’t see the menu on the Google AMP version of the site. I go to appearance -> menu and I don’t have the checkbox to select the AMP menu. I disabled all modules except yours, I switched to Twenty Twenty and it doesn’t work. The site of my client has 17 updates to do (which is not included in the package of the service because she does not want to pay more for the updates ?? ).

This bug can be due to what ?
