The current Plex for Windows app has only existed since a year and a half ago. these are it’s release notes and was first released in August of 2019. Plex for Mac and Windows it’s current version is 1.27.2.1599-7689068b which you said you are using.
the windows store app is a completely different app that we no longer make for a years now… it was only available from the Microsoft app store and no place else. I’m sure there are still old some forum topics about it.
There is another app that runs on Windows Mac linux. Which is Plex Media Player.for HTPCs. its current version number is 2.58 Plex Media Player - #105 by pcalves. This has a desktop mode which looks the same as the current desktop app/web app but it’s desktop mode is no longer worked on. This app was started in 2015.
