After deleting an old world with no timelines, I created a new world and went to create a new timeline. It said I needed a master guild subscription to acsess unlimited timelines. I only want to create one timeline, the first.
The following is a screenshot of the message followed with a link to the screen recording and question I put in the discord help. https://discord.com/channels/348060277989965844/1359731851337666710/1479883676790558852
