For paid games that are free for a limited time, the default option is to have a claimable. So if someone turned it off they they probably did it intentionally for some reason.
Viewing post in Request: Claimable Games for All
Just a quick update on this. Have had many indie devs not understand how claiming works. There's also some confusing languages about 'not always being on sale' under the Creator 'Quality Guidelines'.
Would appreciate an official itch.io blog post and/or FAQ update that explains how claiming works and how to make a free/paid/sale game claimable on the developer side of things.
Thank you very much for your time and attention.
