I was out of town a few days and when I went away I activated vacation mode. I was at 80 reviews then and when I turned it off today I was at 252.
It was activated and didn’t let me do reviews in that time as supposed to, but my reviews still seem to have piled up while it was on.
This happened to me last week, too. I had 130+ reviews when I got back.
Sorry for the trouble! If you send me a DM with the start/end date of your vacation time, I can adjust your reviews.
Didn’t know about that feature, when I went to japan for almost 3 weeks I went back with around 200 reviews to do. What I do in those case, is simply to do a certain number for the next few days and not add any new lessons. Sometimes like 50 every day for 5-6 days until the number of reviews dropped below 50 and then I started taking new grammar points again. Took me around 7 days to get back to my previous state 
I guess I just learned Vacation Mode exists. Cool!
I send a message in the app through feedback.
Is that how it was supposed to be? Thank you 
Sending DM via mobile doesn’t seem to work. When I try it like it is explained in the dm section the letter-icon is showing nowhere when I click on someone’s avatar
This has happened to me every time, I thought that’s how it was supposed to work
Glad to know that was wrong, I hope the devs can fix it.
