Since yesterday, my AnkiDroid app always shows me that all cards from a certain deck are empty, while I can see them normally on the computer. The problem only affects one particular deck, the others work normally.
The text sais:
“Diese Karte ist leer. Verwenden Sie die Option “Leere Karten” aus dem Menü der Stapelübersicht.”
However, I don’t want to delete all the cards, because I spent a lot of time creating them.
I hope you can help me.
