There were some weird disconnect issues today. From the chat at a table I saw others were having the same issue too. Dunno if its related, but for some reason my top set got folded on one table even though I didn't click anywhere near the fold button
Also, could you make the "Remove from waitlist"-button a different color than the one where you ask to be added? Its a different color when its in active when there is an available seat, so I wouldn't imagine it to be difficult to also change the color once you are on the waitlist. (I've accidentally removed myself from the list a few times, as its difficult to notice that the text is different.)
