This happened to me at work earlier today. I opened the Wal Mart.com site and when the pop up Ibotta window opened it said I needed to log in. I had been in it around lunchtime but had closed that window, I was reopening it to look at something else. I tried logging in and even opened Ibotta by typing in the URL and all log in failed. By the time I got home it was fine. I have my passwords remembered here at home and they did not kick me out during all of this at work, everything opened as normal.
