Streak resetting before midnight...
It's still Thursday but I guess when I came to do Duolingo today it was marked as Friday so it thinks I skipped today. So I lost my streak. This is so annoying and happens so much. Is Duolingo defaulted to Eastern Time?
There have been several adjustments to how the clock works. So, I'm not 100% sure how it is working right now. It used to be midnight based on the time zone you were in when you first created your account, and it would not change to suit new time zones you entered. Then the Android app used to change your time zone if you travel. So, like I said, I'm not sure. What you can do, however, is to purchase a streak freeze from the Lingot store, located in the Home tab.
I'm sorry you lost your streak. :(
If you log into the Duolingo website, the Home tab should show you how many hours are left in your day. (If you're viewing the site on a small screen, you may get the "mobile" view by default - you'll need to switch to the "full site" view to see this information).
