You may find yourself getting signed out or logged out of the app through-out the day. To be technical, you are not actually getting logged out. You are having to log in again multiple times a day. Anyway, you can fix this by toggling a simple permission setting on your app (iphone only).
Go to your iphone's settings and choose the app menu. From the app list, locate Kickserv. You will have a list of permissions enabled for the Kickserv app. You are looking for Background app refresh.
Turn Background app refresh: OFF
This keeps the app from trying to maintain your login session while you travel around in various cell coverage areas.
For Android users, the issue is much the same. Though, it is less common and you won't have this same permission available to toggle off. So, for Android it is recommended to NOT leave the app running in the background for extended periods of time. Swipe up on Kickserv from the running apps menu or use whatever action your device offers to close the app when it is not in use. This will allow it to reload throughout the day without needing a refresh to the login session.
