Sent to the DAZ help center:
It is very difficult to log in and to reach my DAZ account because the website’s response time is very long.
Once I am in my account it is also very difficult to reach the checkout page. I have finally reached it and I have tried to buy the items that I have put in my cart.
Since I use PayPal I have been driven to the PayPal website where I had no trouble to log in. Meanwhile when I clicked the button to return to DAZ to achieve the payment, the DAZ website response time was long and when I reached it I saw an error message telling that there was something wrong (wrong PayPal return or something).
I have not tried to check out a second time and I will wait for the issues to be fixed to try again.
It seems that there is no pending transaction or payment anywhere (DAZ or PayPal) therefore everything should be okay.
But of course I report the issue…
