Hi All,
I am new to nopCommerce and followed up the documentation and setup the nopcommerce as Azure AppService. My nopversion is "nopCommerce version 4.40.2"

I even purchased the seven spikes emporium theme and noticed that the app crashes in the Event log of the appservice. I've uninstalled it and no app crashes in the log but still the payments not happening.

I following the following link and setup the paypal smart button plugin.  I've downloaded the paypal smart buttons plugin from nopcommerce.
https://docs.nopcommerce.com/en/getting-started/configure-payments/payment-methods/paypal-smart-payment-buttons.html#3-set-up-the-paypal-developer-dashboard

I tried both the sandbox and live credentials to the appid and secret. I see all the transactions are in pending state in paypal webhook events.

I googled why would the transactions be in pending state in paypal and many say that it could be issue with the webhook app.

I've setup a test webhook and see that the events being fired to it.

My app after paying via paypal still stays on the payment screen.

Going crazy from last two days and couldn't figure out what the issue is.

Do I've to do anything on azure appservice to trust paypal?
Attaching the screenshot of the paypal pending transactions.
