I'm using woocommerce on my website (WP version 3.8.1 running Mystile theme). I'm having trouble getting Paypal to return users to my website when they have an existing account on my site or have made a prior purchase on my site. Instead, these users are taken to a Paypal page and the order remains pending on my site.
I know this isn't an issue relating to the return url, ipn, Paypal or the Payapl settings for my site because new users who sign up and make a purchase in a single session are appropriately returned to the order received page on my site after making their payment. Is this a session/cookies bug in woocommerce? Can anyone tell me what to do about this?
