Dear Community 🙂
Since a few days (no update was the trigger) our "Pay now" button doesn't work anymore, where the pop-up from PayPal should appear. However, there is no error message in the frontend, instead everything stops and the cursor shows that the page is loading.
The following error message is displayed in the Shopware logs:
PayPal: GOT ERROR WHILE REQUEST OF TYPE (POST) TO URL: https://api-m.paypal.com/v1/notifications/webhooks

Even after completely re-installing PayPal including re-creating an app to receive our REST API credentials and re-creating a webhook (both done automatically by Shopware), the frontend shows the same error and the logs also show the same error messages.
I don't understand "Webhook already exists" as we only have one app with one webhook address active in PayPal.
Shopware version: 5.7.6 PayPal version: 6.0.2
I would be very happy, if someone has any idea how to solve.
