Geeze! Going to the AliExpress app to check a package is for when you remember that you ordered something over a month ago and are wondering if it'll arrive soon. Not for regular checking!
Then you look and see it made it to your country last week and give a gentle nod to the app, then close it. Because you know, "any day now, I'll have 1000 of that $0.01 thing."
> then you close it
You mean, then you disconnect the presentation layer.
