Google Analytics required reauthorization every hour

I am accessing Active User count from Google Analytics using Web API, Everything looks fine I get the data but I need to reauthorize Google Analytics every hour. I thought they fixed this issue in new SquaredUp version 5.1.1 by using refresh token instead of access token under the SquaredUp fabric but it doesn’t looks like. I still have to reauthorize Google Analytics.

Any one has any solution for this issue? I would really appreciate if you can provide me any solution for this issue.
