I did not open a savings account back when I did the offer (when it was for $200) so either that's new or I noticed and unchecked the box, I don't remember. I also had no problems linking my chase accounts. Regarding the referral bonus, I can't say forsure, but they should update to the higher offer at some point. That's been my experience. Good luck!
You mean you linked your Chase account on Upgrade's site? When I tried adding Upgrade to my Chase account as an external account it would not populate in the bank search (only their parent company Cross River bank populated, but it did not take my login..)
