The month arrows jump to the top of the page

If on your website when you click on the next/previous month button and then the page has jumped to the top, all you need to do is to put the following CSS code in the MEC Settings > Custom CSS:

.mec-wrap .mec-next-month a,
.mec-wrap .mec-previous-month a {
    pointer-events: none;
    text-decoration: none;
}
