Formatting options not available in Mac Notes app
Recently, I went to the notes app on my mac attempting to make a checklist. However, I noticed that whatever I do, the checklist button (along with most of the other formatting buttons) is greyed out. Whether I highlight existing text, start from a blank note, or anything else, the button and the option in the right click menu is not available. Does anyone else have this issue or could you tell me why it's not available anymore?
For context, my Mac is a 2013 Pro running Catalina because I don't have the space to update to Big Sur.
