Removed and Installed the version as directed earlier, and updated as per instructions: A good question, to which Steam support is slow and often based upon whatever their preformatted guide tells them to ask and respond with. (Reference current issue we have with Steam’s differential update system, which insists that the version of 4 files in our game project are incorrect and insists on replacing them with the previous version of those files. Steam’s response is to contact the game’s support service, which just happens to be me. I wear too many hats these days for a retired old man! The price of being the most experienced dev on the team by a few decades.) As near as I can find out, it is issued to SteamPowered but that is what a fellow dev is saying shows for his. For what it is worth, I get the same message using the Steam application as well as the browser.
