Why are my boards performing so slowly?

Question

I have tried logging in on the phone app, desktop app, and from a web browser. All platforms experience the same issue: My boards are taking a very long time to interact with (moving cards, checking off tasks, creating cards). This has been happening for over a week and has come to a point where it's basically unusable.

I didn't really notice this problem until the new updates started rolling out. Could it be that I have too many cards? I add cards to a "Completed Tasks" list so none of my old cards have been archived.

@Amber Hayes We've since made some several improvements that should reduce or eliminate the performance issues that you're seeing. Would you please reload Trello and let me know if you're now able to use it without issues? Thanks!

@Amber Hayes I apologize for this bad experience, and it is indeed temporary. We are actively working to pinpoint the root cause and fix this for you.

Do you observe this poor performance on all of your boards? Or only on boards with 100+ cards (like the one you are referring to in your other comment)?

Hundreds in the “completed tasks” list. Around 50 in other lists. I don’t know how to get an exact number.
