I have an old project and want to make changes to accept payments from non Paypal users too. I have found that you have to pass: SOLUTIONTYPE=Sole param plus the setting "Account Optional set to On" in the account settings. Also, I have tried to pass LANDINGPAGE=Billing and LOCALECODE=us but it did not change anything. Browser cache was dropped, tried in incognito - also affects nothing. And still, Paypal shows the same page with login prompt. I am starting to think that Paypal disabled that feature and it no longer works. Can anyone confirm that or should I do something else to achieve the result?
