[@missed it] Seems to have been free at least on Aug 30, 2026. Weirdly i missed that offer too and also look daily for new giveaways. Sometimes older giveaways keep being listed as current giveaways on the main page while there is another one that might be newer never replacing the older one. Happened a few times in the past. So better is to check WINDOWS -> GIVEAWAYS / FREEBIES directly instead of only looking on the main page.
I don’t think it will be free again on S0S anytime soon.
