Sometimes, I see that after I finish playing a round of new sentences, the next round contains the exact same set of sentences, as if I had not played them the first time. Details as to where I’ve seen this:
playing on the web rather than on the app
using Chrome on Android
playing sentences from Fluency Fast Track
I’m not sure of the exact frequency with which I see this behavior, but it’s not tremendously rare – perhaps once a week or so.
I think this happened with the last set of FFT sentences that I played today (Thursday, Sept 2, in the morning, Eastern US Time).
Thanks for letting us know! And please be sure to let us know if you notice any other patterns that might help us reproduce the issue. To be sure - this was playing new sentences / not reviews, is that right?
