I'm not getting rewarded for my 10-day streaks
I just reached by 900-day streak today (and my 890-day streak ten days ago). However, I didn't receive any lingot reward for either of those streak achievements.
(I did get rewarded for keeping my seven-day streak that I bought in the Lingots Store.)
Shouldn't I have received 89 lingots for my 890-day streak and 90 lingots for my 900-day streak? Or has the feature of rewarding learners for ten-day streaks been removed?
In theory, yes you should have gotten lingots and I, for one, am certainly still getting lingots at ten-day streak anniversaries.
I've seen a lot of complaints about not getting lingots, lately, though, so I wonder if Duolingo is running another A/B test.
Given the size of your streak, you were probably around the last time Duolingo did that with streak rewards.
I was on the wrong side of that one, so I certainly remember it. As I recall, it went on for weeks and weeks, probably months, before Duolingo apparently decided that giving people lingots for streaks had better results than not doing so. I hope, for you and others, that this (probable) test is shorter.
I'm not getting my lingots either. Missed out on 73 lingots ten days ago and 74 more today. (I'm hoping they'll eventually have some real value.)
I have noticed today in the notification area on the website that I had apparently not received my lingots for 660 and 670 streak days either.
Apparently it is just a bug in the android app. Today I used the web page instead, and received my 75 lingots as expected. Kudos to user FieryCat for suggesting this might be the problem.
