Hey @dduffy
As text is entered into the review notes app, the entries are stored as drafts - a kind of note that’s not accessible in the UI (outside of the review notes app). You’ll see this in action when you move to the next note in the app: the notes entry will flash green, indicating that a draft has been saved.
Draft notes persist until published into actual notes, so if you lose internet connection through the review session any drafts taken up to that point should be saved.
Hope that helps, but let me know if you have any questions!
Cheers,
