Our app supports the current iOS version (18) and the previous version (17). This is to ensure that devices using our app will receive ongoing security updates from Apple. Older iOS versions seldom receive these updates from Apple, which can create potential vulnerabilities and security holes.
This means that access to the new app is restricted to devices eligible to install iOS 17 or newer, which is models launched by Apple in 2018 or later.
