hi David
I tested on 3 different device 2 have this problem and 1 works fine!
I also managed to narrow done the problem it only happens when the website page is scrolled to the top, if you just scroll down a little the menu works fine.
i have made a little video to illustrate this at this link: https://drive.google.com/file/d/1NELpT68wE_eJczOm3Gf5-2rDyeeqch8u/view?usp=sharing
thanks for you help

Hi Gidon,

There seems to be an issue with mobile menus that have sub menus when using a Right-to-left language, and when the Mobile Header is enabled.

I’ve reported this as a bug here: https://github.com/tomusborne/generatepress/issues/406

For now, you can temporarily disable the Mobile Header or remove the sub-menu.

Thank you for reporting this!
