I have been reading tutorials and how-to's around regarding the setup of Paypal Express Checkout on Zen Cart.

Now in 2019 june it seems as if the menus in Paypal have been changed and updated (comparing to when the tutorials have been written). Therefore it is hard to follow the tutorials that I have seen out there, because so much has changed. Is there any updated ones out there that is up to date or could someone please write one?
