Hello, I am handling a site for a client. It has paypal integration via J2Store, available here: https://www.j2store.org/extensions/payment-plugins/paypal-plugin.html I can show relevant code examples. This integration works just fine, for any user checking out with a Paypal account. However, when the users try the guest checkout (i.e. insert credit card details and pay with that, on Paypal), it often doesn't work (but not always!) I get the currency conversion options window, and after that, in most cases, I get this error message. It says "This does not seem to be working at the moment. Try again later". This seems to be some sort of default message (url contains "/checkout/genericError?code=DEFAULT"). I would assume this has to do with security, and thats why it lacks any detail. But I am not sure. Yesterday my first attempt went through, however, 5 following attempts have failed, using 3 different credit cards and also some incognito sessions, and even attempts from my mobile device using 4g ( = different IP). Does anyone have any experience with this? We do not understand how come some times it does go through and other times not. I am not sure, which info can help. I will provide any info you guys ask for!
