Same here. The phone app has not worked in months. The login just loops around. I am able to login via the website, but not the app.
I haven’t noticed any updates to the phone app either. I have also missed out on “app only” coupons because of this.
I guess they don’t find it that important that the app can no longer be used for purchases. On a positive note, it’s saving me money!

Thank you so much and Happy Holidays!
