Hi,
In the portrait mode on Ipad Pro 10.5 header menu turns to desktop after a very quick mobile(hamburger) menu, it happens on category pages, static pages like homepage shows mobile menu correctly.
please help me to fix it. thanks
Please, describe to us your problems in a bit more details. Attach some screenshots and provide us with a list of steps on how to reproduce it on your website.
When I visit homepage everything is fine in menu (pic 1).
Then i go to shop categories page and menu is still mobile for 1-2secs(pic 2), then suddenly it changes to desktop version(pic 3).
We tried this on a real iPad and it works well also. Could you please try to disable all external plugins, child theme and remove all your custom CSS code? Clear your browser cache and check how it works. Also, try to use the Chrome browser on the iPad to test.
