Redirected To Paypal Homepage

For my latest funnel, whenever someone tries to make a purchase, they are directed to Paypal homepage instead. My older funnels are working ok. I have checked it many times and the latest funnel was setup in the same way as my old ones. Could you help look into this? Thank you!

This is happening to me too since yesterday, can someone please assist? Losing many sales because it’s sending people to PayPal home page. Thanks.
