The Okular website lists the Microsoft Store as the preferred installation and update method for Okular on Windows:
The Microsoft Store is the recommended place to install Okular, the version there has been tested by our developers and the Microsoft Store provides seamless updates when new versions are released.
The Okular application in the Microsoft Store is official (published by KDE) but has not been updated in a year (it is at v23.08.1, current release is v24.08.2).
There are no official entries related to Windows or the Microsoft store on the packaging status page to give a hint at who the maintainer might be to contact.
Quick search on here turned up one thread from March with no resolution so wanted to try again.
Anyone know anything about this? Or can anyone recommend follow-up steps?
