Just got off the phone with Customer Service/ Rewards line. Agent initially was unaware of any issues. As noted above, her screen indicates my correct higer lifetime balance. After being placed on hold, she informed that IT is aware of the issue affecting both the website and app. Resolution should be in place within 72 hours.

Didn't ask if that was just resolution for my account since I called in or fixing the actual root cause impacting many of us.

Same issue for me
 

I am down about 150K points as well from about 1,850K liftime, no change in nights. Called and was told the correct number was in the system. Still not seeing an update on the app.

Considering they've had "Best Rate Gauranteed" on the home page of ResidenceInn.com for at least 2 years (still there on the mobile site as I write this), good luck with that.
