Can’t add coupon - login pops up every time – Stop & Shop Review

This app was overall good. But with the new updates, it’s very buggy. Every time I try to clip a coupon, the app brings up a window to sign in. Once credentials are entered, “Success - You’ve been logged in...”, app again prompts to sign in when attempting to clip the coupon. Happens again and again.
