SCRIPT5009: ‘MyPaLoaded’ is undefined (Edge)

Hello WooCommerce MyParcel developers,

On Microsoft Edge version 38.14393.0.0 we get the following error which results in not loading the #myparcel-iframe iframe:

SCRIPT5009: 'MyPaLoaded' is undefined

We use version 2.1.3 of the WooCommerce MyParcel plugin.

The /wp-content/plugins/woocommerce-myparcel/assets/js/wcmp-frontend.js?ver=2.1.3 file which defines the MyPaLoaded function is loaded correctly.

https://github.com/myparcelnl/woocommerce-myparcel/blob/v2.1.3/assets/js/wcmp-frontend.js#L27-L31

It is working correctly in the following browsers:

• Google Chrome » 56.0.2924.87 (64-bit)
• Firefox » 51.0.1
• Safarai » 10.0.3 (12602.4.8)

Is this something you can reproduce and fix?

Microsoft Edge 38.14393.0.0
Microsoft EdgeHTML 14.14393

I saw there was also a support topic on WordPress.org about issues on mobile devices:

But it look likes like version v2.1.4-beta1 is not fixing this issue.
