fanduel live blackjack seat reserved my balance after i left table

so i dip into live blackjack for a session, find a seat, toss down a few chips, and then decide i gotta bounce. exit the table, close the tab, but i check my balance later and it’s like my chips stayed there partying without me. looks like my seat stayed “reserved” or something, holding my balance hostage. anybody else run into this? is there some unwritten rule about actually clicking a certain button to cash out, or do you just gotta wait till the server gods decide you’re gone?
