After Build: 2 Web apps in parallel after build

i just deployed a new version as wab app several hours ago and its already in delivered status.
What i do not understand:
Accessing it with a edge browser i get the new version.
Accessing with chrome browser i still get the old version.
I already deleted the cache.

How this is possible that 2 versions “work” in parallel
and how can i get the “newest” version in a browser?

Thats my appid AppGyver - Composer Pro

Sometimes it’s happened to me (I don’t know why). I solved erasing the all history of the Chrome browser (not only the cache).
