In metropolitan areas, people want to be close but not too close to train/metro stations or railroad/tunnels. 5-10 minute walk is ideal. Anything closer, people have vibration/noise and crowd/security concerns.
In US suburbs, a lot of people are going to drive even if they live next to a train station. So there’s no convenience or property value benefits. To them, they only see downsides.
If you need access to both apps from China and websites/apps from outside China, non-Apple devices have been difficult before this, primarily due to push notification infrastructure.
This makes it more difficult. But I don’t think it matters given how difficult it was prior to this.
