I posted my experience on another thread, but my pop-up bonus was invalidated because of a withdrawal. I had completed my PPA bonus. The next day, I withdrew $500, intending to redeposit it for the pop-up bonus (15UPTO75MORE). The bonus showed up on my bonus page as "Elapsed."

When I called PP support, the rep told me that I was not allowed to withdraw, then redeposit for the pop-up bonus. So they are keeping track. They manually credited the bonus to me, BTW.
