Issues with plugins when update is available

Hello there,

We have purchased two licenses for your WooCommerce Email Template Customizer.

We have notice that when there is an update available, the plugins starts malfunctioning.

The templates stop working properly and some elements, such as the backgrounds and borders shown incorrectly.

As soon as we update the plugin everything start working fine again.

We have tried enabling the auto update but it did not resolve the issue.

Any suggestions?

Best regards

Carlos A Iglesias
