I pressed hard for the first review of a card, so it is in the learning stage. The next day, I was reviewing in AnkiWeb and reached the card to notice that the number of cards to review (green) is underlined (active) when it is 0, but I’m in the process of learning the card. It was the last card of the day, so I returned home to look at the same card on the desktop version of Anki, and it correctly identified the card as one in the process of learning and underlined the 1 card left in red. This is a screenshot of AnkiWeb and Anki desktop in sync at the same time:
This is a pretty minor bug, and it might be related to the recent FSRS update because I haven’t seen it before. I also have a backup of my collection in case anyone needs it, but I’d imagine it’s a simple fix.
Let’s allow first that it might just be a display/caching issue.
You don’t say what your learning steps are? It seems like it would be relevant whether this card was on a learning step of your own choosing – and so definitely an interday Learn card (since it has already been given a 1d delay since yesterday) – or if you have turned over the steps to FSRS 5 – and this card is in the newly introduced gray area of still-in-Learn-but-with-FSRS-scheduling.
If you can show us the Card Info from after that next study, that will tell us the card’s state coming into that study.
My learning steps are 9h (and I noticed the issue on the day after the first learning step), and this is the card after the next review (two days after the first learning step):
I’m pretty sure it wasn’t a display issue, as this was the code that showed the card as an active review:
I also don’t see how it could be a caching issue at the moment, as I displayed the card on an iPad in AnkiWeb, Anki desktop, AnkiWeb on my PC, and AnkiDroid (which also thought the card was in the learn stage).
Thanks for that additional information! Knowing that you have learning steps (or at least 1), and that the card was definitely in Learn (on a ~14h Hard step that crossed the day boundary) will hopefully help the Dev track down what the issue is.
You said you have a backup of your collection - could you possibly provide that to me via something like a Google Drive link in a private message? If you can also point out the card in question, I’ll try to reproduce the issue.
