Good but not great for the price

Really great format, love the pronunciation feedback but some flaws that really annoy me:
1. App constantly logs me out and I have to waste my time typing my email address and password all over again! Its a fingerprint enabled iPhone! Use it!
2. Almost every 2-3 times I have to "restore purchases" seriously ?? Im becoming frustrated
3. The downloads for offline use are slow to download, disappear and then take too long to download again!

I feel like these are basic app principles. And some pretty annoying flaws when I spend $300CAD on it- I hope they get fixed bc this app does deserve 5 star otherwise
