Plugin has to send to PayPal the language from the nop store.

Open the file PaymentInfo.cshtml

            "placeholder": "ppplus",
            "mode": "@Model.Mode",
//            "language": "de_DE",
//            "country": "DE",
            "language": "@Model.Language",

            "showPuiOnSandbox":"true",
            showLoadingIndicator: true,
            onLoad: function() {
                $('#ppplus iframe').width('100%');

What plugin release do you use?
Is it 1.01?
I can't duplicate this bug on my test store.
Open this product in admin mode and make print screen. I want to see it settings.

Open plugin configure page  and change the parameter "Number of products".

I added it. Download new release and replace Create.cshtml file
Try and write me about result.

You changed the native cshtml file ArticleTemplate.Default.cshtml

Send me it.
You added picture manually and used
Model.PictureModel.ImageUrl
Try to use
Model.PictureModel.FullSizeImageUrl

I think I can do such plugin for my marketplace. It's not difficult.
It will cost 400$.

I can't understand the logic with "we have a warehouse for each pickup location".

Can you make print screen and send me your order-shipment logic and send me them?

It will custom solution. I am not sure that I'll sell this plugin another vendors.
I can do such plugin.
Can you describe the logic of "rules"?

I can create shipment in automatic mode but I wan to know about these rules..

Yes.
Please send it and I'll include this XML file in plugin.
