Cognito - User Asked to Login to App Constantly

I am using AWSMobileClient on an Android App with a Cognito User Pool. I have set the Refresh Token Expiry to 3650 days and the Access Token Expiration to 1 day and the ID Token expiration to 60 minutes. I do not want my users to have to login to my app after the first login is successful. My users are randomly experiencing an issue where they are asked to login to the app again. Please assist to advise what other settings need to be changed or what else I can investigate to find the problem.
