Cannot move cards in or out of a specific list

[Savanna Timofei]

We have a list called "done" that is failing to move cards in or out of. It's not 100% of the time but for 2 days its been approx 90% of the time. 

The list did have approx 950 cards in it so assumed that was the issue. we have archived 700 or so but the issue still stands. 

Every other list is fine and we can move cards freely. 

We get an error saying failed to move card.

Hi @Savanna Timofei ,

I guess this could be sync lag and a performance issue due to a large number of cards within the list.

🤔 You can maybe try some of these things:

1. Move the List to a New Board: Click the list menu (...) and select Move List. Moving the entire list to a temporary "Archive Board" can clear the stuck metadata on your primary board.

2. Copy the List: Instead of moving cards, try copying the "Done" list (without the cards) to create a fresh, empty version, then move new cards into that one.

3. Hard Refresh: Use Cmd+Shift+R (Mac) or Ctrl+F5 (Windows) to ensure your browser isn't relying on a cached, "heavy" version of the board.

4. Mobile Workaround: Try moving a card using the Trello Mobile App. Mobile often uses different API endpoints that can bypass web-rendering bottleneck

*the list of workarounds is partially AI-generated; I can't say if these will actually work

Cheers,
Tobi
