I have some tips for those of you who linked their vcc to paypal. I know it's a little offtopic, however it is something I searched for many hours and did not find a response for. So I am sure I'd help a lot of members. Here it is:

If you link a VISA VCC from Wirex and verify it with the code, you will probably won't be able to withdraw to the card for a time period of minimum 5 days and possibly 1-2 weeks. You will get an "Internal Server Error" every time you enter the amount and click "Continue". That error is BS.
In fact, Paypal is trying to "protect" the account. By adding a card, it is possible an attacker would be able to cashout the balance through an anonymous VCC (and paypal is aware of the card).

Solution:

There is no ACTUAL solution, but here are some tips:
- the old paypal.com/wdfunds link solution DOES NOT WORK; you'll get a similar error
- the paypal app won't work either; there's no option to wd to card using the app
- do not try to withdraw every single day! leave the account untouched with funds in it for a couple of days (3-5) and then try; if you get that error again, repeat after 3-5 days until you will be finally allowed to withdraw
- sending and receiving various transfers to/from trusted paypal addresses might also help
- alternatively, you can call Paypal support and they will try to reset that, however it is not guaranteed. Paypal support might also lie to you and after the call could imply limits to your account (that depends on your history and many other variables).

I hope I could help.
