I have added the following CSS as suggested:
.etheme-sticky-panel.outside {
opacity: 1;
visibility: visible;
transform: none;
}
But now the bottom of the homescreen is covered by the mobile panel. You can’t see the reviews and prices of the items at the bottom of the screen. Also see the ‘back to top’ button, it’s not possible to scroll to the very bottom of the screen. Thank you for your help.
