Yesterday I gathered my daily 50 xp using the iOS version but the app took a while to load when i completed the final exercise and apparently it didn't actually register correctly because today it shows only 40xp and I lost the streak. I've been keeping my streak unbroken ever since I started using Duolingo and this has been helping me staying motivated a great deal even on bad/busy days so this is a real bummer..is there any way to verify the error and restore my streak?
