Hi Gunnar-Haslinger,
1) For packaged apps, i.e., UWP/AppX/MSIX apps, the Store doesn't have a discrete version tracking mechanism. It only knows the latest available and published to the Store and so will give you the latest versions published. What's your desired end result when using this switch (besides the obvious)?
2) Using the search tools at your disposal, you should be able to find the proper apps that work on the different platforms. Looking at the downloads in your screenshots above, multiple versions were downloaded including the following: 2017.920.157.2000, 2022.2401.9.0, 2016.1010.1800.200, 2017.510.2201.2000, 2018.421.8.1000, 2021.2101.28.0, 2022.2304. I don't know what the difference between each of these is as that's defined by the app publisher. I also don't know why the app publisher is making this many different version available. I fully appreciate that's not helpful and adds confusion, but this is not something WinGet can disambiguate and will take a bit of research for apps where this is the case.
3) Paid apps cannot be downloaded (or installed) using WinGet. This is not anything that WinGet can dictate or change.
4) Make sure the account you are using is properly authenticated to Entra and avoid using an elevated command prompt. If this persists across multiple apps and identities, please open a support case so that we can investigate.
