I have the same Issue on Android and IOS. When i click to open (1.touch) and touch to scroll down to the last menupoint(2.touch) it disappear. Its OK when i don’t have to scroll. Is there a possible setting?
I have changed the options in the Meris Lite Options (Both Option disabled: Active Sticky Header & Display site name in sticky header)
The created menu are the primary menu. I recreated the menu but the problem on mobile are still existing.
