Lost tab settings after upgrading

Still have tab settings (and font settings) in existing project but when I add a chapter in current project my tab key works like the enter key. Can’t find how to correct this.

It finally dawned on me how to fix this. Just temporarily confused by the upgrade. Go to preferences, formatting, main text.

Ah, yes, 2.0 has completely difference preferences - glad you got it sorted.
All the best,
