Premium Deluxe content missing

I recently purchased MSFS premium deluxe, but the sim only shows the standard edition software. I tried the workaround for windows 2004 but I am unable to set my computer to a previous version since it has been more than 10 days ago since the update. The windows store says that MSFS premium deluxe does not work on this device.
If there is anything else I can try, please let me know.
