Will the tips for the Latin course be available on the app? I can only access them via the website. Is there something wrong with my version of the app?
Mobile Tips are only available in a few languages, and Latin isn't one of them. Tips are written by Duo's staff and/or paid contractors. You can read more about Tips here.
Tips and Notes for are written by course contributors, who are unpaid volunteers. The T&N are what are available on the browser version of Duolingo for most (but not all) courses. There are even some courses that currently have both mobile Tips (located on mobile apps) and Tips & Notes (located on the web browser version) which have different content.
