I searched this site and it seems the last post regarding this problem was a year ago so I thought I'd bring it back up.
Why, oh why does the Marriott app forget about me? I open it and it acts like it doesn't know who I am.
I go to the menu and "Sign Out" is available. If "Sign Out" is available, that indicates I'm signed in, but alas, I must sign out, then sign in for it to find me again.
Why can't this be fixed. My fellow iPhone travelers tell me this is not an issue on their phones. Why is it on my Samsung s7 and on the previous 3 android phones I've had?
