Good—seems feedback option not working – L-Lingo Learn Serbian Review

Very good app. The only thing I have noticed, is that at least on my device, the "send feedback" button within the app's settings does nothing, whereas the "rate app" does. Super minor, but fyi. Granted I'm only on the 8th lesson, and don't know how in depth the grammar explanation goes yet—due to how difficult it has been for me to find concisely stated and clearly explained and organized information about Serbian grammar online, I would be very happy to see this app incorporate this. Or perhaps, if this is not unreasonable, guided quizzes or exercises detailing the conjugation of verbs, phonetic changes, etc. Thanks!
