A minor bug really, but still deserves your attention. The app keeps telling me that I am on 2 day streak, although it was 3 and now 4.
This happens to me too. I am on a 10+ day streak but it says 4. If it can help, the streak apparently got reset when on a day I did my workout at 1AM and then the following day I did it around 11PM (I.e. at >24 hours from the last one).
I am experiencing this also on Android.
