OC 3.0.3.8. Success (Order Placed) page not displaying on mobile after Paypal payment.

Hi,
When orders are placed on desktop and tablet and paid for by Paypal Commerce Platform, everything works fine, and once Paypal is done, the website is redirected to the success page. But this doesn't happen on phone - once PayPal is finished, the website stays on the checkout page with the item still in the basket, so customers aren't immediately sure whether an order has been placed. This occurs in Safari and Chrome, so I don't think it's a browser issue. I believe it is a PayPal issue, as I just successfully placed a test order using C.O.D. So looks like Paypal is not redirecting on mobile. Does anyone know where to start looking? Or is a 'contact the developer' job. FYI, using the default theme.
TIA.

I think you should contact the author of the PayPal Checkout Integration, which is Dreamvention. The author's website is at: https://dreamvention.com/

I am experiencing the same problems, did you have any more insights into this? Its difficult to debug as this seems to only happen occassionaly. I am on the extension version 2.2.0.0 though.
