The PayPal Plus offer used by users of a PayPal Germany account has been discontinued in favour of the PayPal Checkout solution.
Starting with version 5.7.0, the official PayPal module allows merchants to adapt to this change.
To use the PayPal module in version 5.X, it is necessary to use PrestaShop versions greater than or equal to 1.7.0
Older versions of PrestaShop are not compatible with the latest features of the PayPal module.
The new version of the module including PayPal Checkout also integrates new payment methods:

PUI (Payment Upon Invoice) is a widely used payment method in Germany. It allows customers to purchase products and pay after delivery if they are satisfied with the items and wish to keep them. Users of the module with a PayPal Business Germany account will need to configure the module to allow PayPal to synchronise the tracking numbers of orders sent. In the event of a dispute between the merchant and the buyer, the tracking number is used by PayPal to verify whether the package was shipped to the buyer. This configuration is therefore mandatory. If the carriers are not synchronised, the PayPal payment method will not be displayed on the site. To configure the PUI, click on the "Partner referral sign-up link" button in the "Account Settings" section, "Setup" tab.
Then, synchronise PrestaShop carriers to PayPal couriers in the "Experience" tab of the module configuration page.
Save the changes. The module will indicate that PUI is active.
NB: The PUI option will not be visible in the checkout if the webhooks are disabled in the module.
