Plugin has internal PictureService and creates new pictures without watermark and ALL pictures in JPG format.
I think you have a task/job and removed new pictures. It's not a problem.
Open the plugin configure page and enable 'Use external picture service'. Plugin will use Picture Service from your Nop store.

No, plugin adds tracking code on "Checkout Completed" (url yourstore.com/checkout/completed/{orderid})
Plugin adds tracking code only ONE time to one order. It's important.
Create fake order and try it.

If you skip checkout completed page and move to 'orderdetails page' your store will not send tracking code to Google Tag Manager.
Enable "Checkout Completed" page and check it.

P.S.
If you can't enable it and want to redirect customer to order details page I can add tracking code in order detail page too...

Yes.
If you use PayPal Express Checkout from cart page plugin sends to PayPal product list and doesn't send shipping and payment fees.
It's important!!!
You can see on cart page that NopCommerce didn't calculate shipment amount and you saw. 'Calculated during checkout'.

PayPal uses internal shipment rules (fees) for PayPal Express Checkout.

Read this document and add new shipment rule 10$.

PayPal will charge shipping fee itself now (for PayPal Express Checkout!!!) if the store doesn't send shipment fee.

Plugin uses another kernel for picture optimization now.

I think I found the problem.
Send me your TAX settings  (inc or excl TAX) and if you use 'ForceTaxExclusionFromOrderSubtotal'.
I'll calculate discount  for product with TAX... maybe we'll have a problem with rounding...

I think I'll add new parameter  'Requires coupon code'.

You can download any plugins from its own pages without registrations.

I have fixed this bug.
Release 1.02.
Thank you.

Download new release of plugin 2.09. We have fixed this bug. Thank you.

We use this API for checking parcel status.

But plugin checks it itself automatically in back mode.
Do you want to add support checking tracking number from your site for your customers?

Nop 3.90 has ACL for payment method (plugins). Maybe you use this feature...
