Locked? what do you mean? How can we help you?
No offense, probably cant help. I figured out why its locked. I followed for free so everything is locked. Its the same for all the devs I tried following. I have found that if you dont pay for a certain membership, on a dev site, you dont get access to some of the content. Its a bit of a bummer, but I’ll stick it out here on Itch or steam
