If this was your first time trying to withdraw, you need to wait at least 2 days before withdrawing.
Unfortunately, your account is probably locked. You will need to open a request and have them check your account. Be aware it can take several days for them to respond, so don't open multiple requests. That just slows them down.
To open a request, go to Account in the app and then to Help. You can open a request from the top of the screen.
Good luck.
