The post indicates that the community member will investigate something, and thanks someone. The comments discuss the behavior of an app on different platforms, the version of the app, and the location of the "About" page on Windows. The community members are unable to find the version information and there is no standard location for the "About" window on Windows. There is no explicitly marked answer in the provided information.
I just checked with another app that installed as an app. The only thing I find is App Info, but it doesn't contain the version. Where do I find the version when running WS in the normal Browser window?
