[reopening] “Ignore reviews before”-setting lost during syncing

I use the “Ignore reviews before”-setting to have FSRS ignore the older part of my review history. What I have noticed a bug, that under some circumstances, this setting doesn’t get synced or gets reset.

I have posted this before and an ankiweb dev has said that:

Sadly, the issue remains to this day and the previous topic has been automatically closed without the possibility of reopening it. This is why I write a new post to bring this issue to attention.


  1. During a full sync, no matter what is pushed to ankiweb, the date will reset to 1970/1/1.
  2. Sometimes, a value will just outright not appear on AnkiDroid (though I don’t know where it happens). Might also be a bug with AnkiDroid, but I currently cannot check. (this seems to be fixed now, or at least didn’t happen again)

Reproducing the bug

  1. Change the “Ignore reviews before” value in the settings of a group.
  2. Sync with ankiweb
  3. Force oneway sync from ankiweb, replacing the local state.
  4. Setting has reset to 1970/1/1.

You use the word “sometimes” so does it mean the reproduction steps don’t always work?

Sorry for the misunderstanding, the sometimes referred to the second condition, which I couldn’t really reproduce.

I haven’t found time to push the changes to AnkiWeb yet I’m afraid (they’re currently blocked by some unrelated breakage). It’s still on my radar.


I completely understand! I just saw that the last topic is closed and cannot be posted on anymore, so I wanted to “reopen” it, as it is still an issue.
