Small Loading Gif Error

Using SendGrid version 1.3.1, I have an error on my wp-admin dashboard in the SendGrid stats widget area.

The “loading” gif has an incorrect URL caused by an issue in the code at line 14 of sendgrid-email-delivery-simplified/view/partials/sendgrid_stats_widget.php, which should instead be:

<div class="loading"><img src="<?php echo plugin_dir_url(__FILE__); ?>../images/loader.gif" style="width: 15px; height: 15px;" /></div>
