login in directly to post

Here is what I would like… I want to go directly from the login screen to the post my users re trying to access.
Currently it goes from login to dash board then back to home page then they can read the article they have chosen. It has become big issue with some of my members and have lost a couple because they got so confused.
currently I am using the free version of paid memberships pro for my subscribers
but i dont know if that is the issue or not
I am very much the novice at wordpress
