Hi, when I add cards and go through them once they disappear. I uninstalled, and restarted. They came back and I went through them again and they’ve disappeared again?
After the very first review, the new cards will be presented to you only after some short period of time, which may vary depending on your settings. To make sure that they’re actually disappearing and not getting delayed, please check your Browser to see if the cards are there.
