Hellow,

I'am newbi on paypal.

now I am working for auto return in sandbox.

somedays worked from the day start.

(I did autoreturn to On, and registered Return URL , and Payment Data Transfer to ON, so worked)

but now , don't to to return after payment . I didn't change anything in config.

So I setted again, and again.

But url never changed for return url.

just It was on paypal result page 

"Your payment was completed. To continue shopping, please return to the merchant."

if you know why it is, please teach me.

thank you.
