Recently, the image uploader in the community was upgraded to the latest version. Since then, we are experiencing issues with newly uploaded VI Snippets. While this issue is being investigated, we ask that you please attach the PNG files for the VI Snippets so that they can be used properly.
Looking for a workaround? Refer to this post from Hooovahh.
