I wonder why do applications nowadays have to be updated every time? Most of the time i dont update them, i dont have time in updating applications manually and i also dont put them into an auto-update setting because i dont want my data to be eaten by updating but if i wont update them sometimes cant use them properly and when i update them, I dont really see changes, it seems to me that everything remains the same.
They are just installing the updated version which they say is a better one. When the developers find a bug or they want to enhance a certain application. They do this update. The new one cannot be differentiated from the old one because they do little revisions only. I have work with some programmers and they do this from time to time.
And to better wind down any cloud of confusion on application updates, please be reminded that though PWAs boast of a no-need-to-update feature, content related updates will still take place every now and then which will add up to the loading time of any PWA (though guaranteed to be much faster of course than a native app update).
Thus, we can say that updates will not be erased radically, rather, PWAs updates are not visible to us anymore nor we should ever learn that an update took place as we wait for the PWA to load.
