Just had a weird bug. I’ll explain the steps to hopefully help troubleshooting:
I completed 100~ reviews this morning on my desktop.
Shortly after I checked the app and the learn/review buttons were greyed out (subscription needed).
Throughout the day I saw my reviews building behind the greyed out review button, getting to 70ish.
Just now I bought another month (through the webpage, not the app this time) and it unlocked my 70 reviews.
I did two, got the first wrong and the second right, after which it forced me to the summary page giving 50%, and returning to the dashboard I then only had one review.
Clicking that, it was the one I got wrong but after getting it right this time it went to the summary screen and displayed 0% correct.
Now I have no reviews, but also I have no reviews scheduled for the rest of the day and tomorrow…








I was mostly chiming in to say I had also seen and reported this
