Broken layout on Gmail iOS & Automatic “Cancelled Order” emails not

Hello VillaTheme Support Team,

I am experiencing two issues with the Email Template Customizer plugin after a recent update.

Issue 1: Broken layout on mobile (Gmail app on iPhone)
The email templates are no longer responsive and look distorted/misaligned when viewed in the Gmail app on iOS. I have attached a screenshot showing how it currently looks.

Issue 2: “Cancelled Order” emails are not sending automatically
The “Cancelled Order” email is not being dispatched to customers when the system automatically cancels an order (i.e., when the status changes automatically from “Pending payment” to “Cancelled” after the time limit expires).
Please note: The email does send correctly if I manually change the order status to “Cancelled” in the WooCommerce backend. I have attached a screenshot regarding this issue as well.

My Environment Details:
Website: sofasandfriends.co.uk
WooCommerce Version: 10.3.8
Email Template Customizer Version: 1.2.18
Could you please look into these bugs and advise on a fix or a temporary workaround?

Thank you in advance for your help.
