Ignore the above, working fine in 2.2.2. Thumbnails seem to take a while to appear initially.
I am having the same issue with the following shortcode.
[Youtube_Channel_Gallery feed=”playlist” user=”PLL0fOoZ8DvxEX0UMfvvnS-QEyJn_gCmCQ” feedorder=”asc” videowidth=”500″ ratio=”16×9″ theme=”light” color=”white” quality=”small” autoplay=”1″ rel=”1″ showinfo=”1″ maxitems=”50″ thumbwidth=”200″ thumbratio=”16×9″ thumbcolumns=”1″ title=”1″ description=”1″ thumbnail_alignment=”left” descriptionwordsnumber=”10″ link_window=”0″ player=”0″]
I just got that same email from Google about updating to v2. Would be great if there could be an update. I will have a look myself this weekend if you need a hand.
