Recently, before Apple's iPhone 12 went on sale, I rushed to Sony's xperia 5 II, which was first launched on 10/07. As an Apple user for many years, after the battery door incident, I don't really like Apple's style of asking for money. For a developer, I always hope that he can support PWA, but he has not done it for several years. Guess I also know that for the profit of their store, they just don't support it... Then I will switch to Android...
