Hi, I have iPhone Xs with iOs 14.6
I have checked also the woodmart demo, and there is the same issue.
Please take a look at screenshots

when i press the menu buttons (both from the top left and bottom bar), the my account and cart, it simply shows the black screen.
When i press the filter button, the panel appears on the half bottom side.
I have also cleared the browsers cache of the iphone. (tested on safari and chrome apps)
