Lot of new iOS/iPadOS versions add new bugs at the OS level for home screen web apps (standalone apps). For example, on latest versions, when you search the shortcut in the hone screen, it appears but when clicked, it opens the URL in Safari and not within the standalone experience. This is just one example of many (some of them reported for years, some other maybe not reported), but it feels that with every Safari version or iOS/iPad version no one is making a basic UI test over home screen web apps. These issues seems simple to solve if someone takes ownership of the platform and decide to test it on every new version
