I would explain the process to withdraw your payout, it's not very clear cut, but as you have done it already that cannot be the issue here.
What device are you using? If the app or mobile browser, they can be glitchy, if using switch if you can to a laptop / PC and try Chrome that seems to work well, try from there.
If there is still an issue contact eBay Customer Services.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.
