Hi everyone, I figured it out.
Here is the solution to remove the dark blur overlay and lock symbol on lesson thumbnails when there is a paywall active.
Insert into Custom CSS:
.course-list__grid .course-list__grid-course-item-thumbnail-container .course-list__grid-course-item-thumbnail[data-private-mode="true"] .course-list__grid-course-item-lock-icon-overlay {
display: none !important;
}
.course-list__grid .course-list__grid-course-item-thumbnail-container .course-list__grid-course-item-thumbnail[data-private-mode="true"]::before {
content: '';
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-position: inherit;
background-image: inherit;
background-size: inherit;
filter: blur(0px) brightness(1) !important;
transform: scale(1.03);
}
