I finally saw the bonus points hit today, although it was difficult to verify at first because the app had all my points breakdown zeroed out since my January statement, and does not seem to show bonuses in the UR transaction list. But since I have been checking semi-regularly I could tell how much my points total increased and the amount seemed roughly correct. My statement just closed, but don't know if that timing was simply a coincidence.

And after going back and forth between screens in the app I finally stumbled across a view that showed 20k bonus points that I swear had shown 0 just seconds before, so maybe some background XHR load failed the first time /shrug

I actually got the 20k/10k offer on multiple cards and was able to enroll all of them, but then I noticed the fine print said eligibility was limited to people who had not used Chase Travel since such-and-such date, which maybe implies they only intend you to use it once. Who knows how their IT actually would have handled it, but I decided not to FAFO.
