I'm not sure then unfortunately, as the Simulator is up todate with the ingame funishing, for wallpapers in case they are perhaps paywall item, make sure you have the two boxes on the side of the Furniture box (where you select items), to display all available items, if unchecked some items will be hidden ^^
The itch app version consistently does not work for me no matter what I do. It is always one or more versions behind the website release which then bricks builds. I immediately had to uninstall the itch app. So, yeah. You guys need to investigate why it is that multiple people can't get the itch app version of makeplace to update properly to the current version. I downloaded it for convenience and regretted it immediately and frantically had to roll it back. :/
I'm sorry to hear you've having trouble updating Makeplace through Itch.io. We are aware that some users are experience this issue. The most common fix has been to turn off/on the wi-fi and redownload the update, for others, restarting the computer did the trick.
