Days of reviews magically disappeared


I just synched my progress from my phone to my desktop version of Anki. I did all my cards yesterday. However Anki shows me that I studied zero cards yersterday (on mobile and desktop). I also noticed that that I have to do literally the same cards as yesterday with their normal intervals. The cards that would actually be due today do not show up… I am very confused about where that error comes from. I did not force a synch in any direction or whatever…

I use the latest android app and for desktop I use
Version ⁨2.1.49 (dc80804a)⁩
Python 3.8.6 Qt 5.14.2 PyQt 5.14.2

I do not have any add ons installed that change scheduling or whatever.

You’re not using the latest Anki version, and using AnkiDroid, so it’s not clear where the issue lies. You may be able to recover your data from a backup: Restoring an Automatic Backup (Recovering from Data Loss) - Frequently Asked Questions
