Hello, I have had this problem often. Every time I go to scan something using scannable, I get the introduction, I also get the invitation to sign in. Wouldn't be a problem other than I have two factor authentication turned on, which means I have to go to my authenticator app. Adds one to 2 minutes every time I need to sign into scannable. By that time normally I have missed the opportunity to scan things.
Please advise if this is a cookie thing, or if I need to have some kind of app analytics turned on.
