I tried several times on 3 different days to support OGS via Paypal. But every time I checked out at Paypal, it told me that the booking was not successful. I use Paypal all the time, and I never had any issues like this. So I think the problem must be on your (OGS) side. I can’t provide much more information I think. I accepted the terms of service and already confirmed the transaction and after that, it told me there was an error. That’s all I know.
