Hey chelawonk,
the overlays on tiles are displayed by default on smaller screens because this is a good UX practice: since there is not “mouse hover” event on touch devices, the overlays should be visible to enable the visitors to encounter the same information on smartphones and tablets. There is no back-end setting to disable this, yet you can customize the theme’s code by altering line 599 in the theme’s “header-functions.php” file.
Sincerely,
Andrii / Satori Studio
