Tracking is not in sync sometimes with eBay and with a Bank Holiday it may not show delivery for a few days.
By mid week if it's still not showing delivered, contact eBay Customer Services with the tracking details, for your payout to be released sooner.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open 8 a.m. - 10 p.m. on weekdays
9 a.m. - 6 p.m. on weekends.
Automated agents will be available on chat outside of the above hours.
I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
