You can request it once every 24 hours. Click on the amount of money owed to you in the top right corner of the main dash. Then click the yellow box after that.
Yeah I don't think that's an option for my account. More detailed info says that funds can be on hold for up to 14 days and then they are transferred "on the subsequent settlement date". So perhaps it can be requested after those 14 days are up and it's no longer part of the "unavailable balance".
I have been selling on here for a few years now but I have a very minuscule amount of feedback. Maybe 1-2% of people leave feedback.
