Welcome to the Shopify Community! Please share your store URL and password (if it’s password-protected), so I can check and provide you with the exact solution.
You may consider report it in .dev forum like I did for 3.3.0 – there is a higher chance Shopify people will see that.
However – I do not seem to have this problem in my test store.
Can you share a (preview)link to this theme in your store and a preview password if one is set?
But this is an inherent problem with hover-based menus – visitor needs to be careful moving their mice…
You may alleviate this a little by adding an “extension” like the gray area on the screenshot below where green arrows represent valid mouse trails which would activate neighbouring menu items otherwise:
Yes.
Either add an “extension” similar to one I’ve suggested in the post linked above, or/and move the mega-menu higher so that there is no need to go down that much first.
Of course having the top level menu at the center, but mega-menu sub-menus too far left (because mega-menu takes full screen width) does not help…
