Gmail may be kicking you out due to several reasons. First, make sure cookies are enabled in your browser as some antivirus or related software may delete them. If your cookies are enabled, try clearing your browser's cache. Additionally, staying signed in or out of your Google Account can also affect this issue. If you're using the Gmail app on your iPhone, closing the app and updating it to the latest version can help resolve the problem. Ensure that your WiFi network connection is stable and try turning Airplane Mode on and off. Restarting your iPhone or performing a soft reset of network settings may also fix the Gmail app crashing issue. Taking these quick and simple steps can help you stop Gmail from kicking you out and ensure a smoother user experience.
