This presents a unique challenge in pushing out new features and updates over time. As a user, you will need to manually keep track of updates and make sure the latest update is installed. To simplify this, the new Safe Browser automatically prompts when an update is available. You could also check if an update is available from the browser's menu.
At Mobicip, we constantly strive to make your experience more intuitive, and we hope this feature helps you in keeping the app up to date.
