how do i change my trellos visibility

[Hi]

this is my first time making a post but, ive switched between three different devices trying to change my workspace's visibility and every time it switches back to workspace visible. I have tried testing on my other board to see if i could switch the visibility and it works fine. But for some reason this trello refuses to change its visibility settings no matter how many times i try to refresh it, or move devices. I searched through a bunch of threads hoping someone else has this problem but no luck, is there anything i can do to fix this????

You can go to your workspace settings, where there's the 'Workspace Visibility' section, and change it to 'Public' so that people can access your Trello board.
