> First thing you learn when getting used to Notion is that every page you share should be locked from editing!
> The next problem with edit lock is that you can't unlock the page just for you. So you are a good user of Notion and keep all pages locked from editing. But every time you want to modify a page, you unlock it and everyone can (unintentionally) modify it while you're editing.
> Adding or editing content isn't the only case when you need your page to be unlocked. It is impossible to add comments on locked page.
^^^ These quotes are all wrong. You don't lock your document. When you share a doc, configure the access rights (edit/comment/view only, similar to what you do when sharing a Google doc).
