Just noticed (and confirmed by others) that the you can’t navigate to apps from the vendors pages. Simply go to any vendor page on the marketplace and click on an app’s tile. It will not go anywhere. However clicking on the tile from a search result works. So far, it only fails if you click on the tile from the vendor page.
@yvesriel@boris@david.toussaint@raimonds.simanovskis thanks all for flagging this issue. We have identified the bug and implemented the fix as necessary. Could you please try again and confirm it is working as expected now?
