Express Checkout Integration: Users stopped being redirected back to merchant site in mid January

[torotil]

In mid-January (2019-01-16) users on my site stopped being redirected back to my site after a successful payment. Was there any change that could have this effect?

- I’m using this the paypal_payment drupal module. There was no update rolled out during these days.

- I can clearly see that the redirect worked before (in almost 100% of all cases) and now it does not at all.

- This seems to only affect live payment methods. I was not able to reproduce this using the test account.

Any other suggestions for debugging this?

Never mind. It seems the redirect is happening (HTTP server logs) it just stopped registering in the database.
