@vemic - I just tested from the same version Firefox (64-bit, Windows 11) and both the Ctrl-Z and Undo action from the left toolbar in the the Miro UI.

For this first test, I

• press the N key to quickly create a new sticky note
• Next, while still in edit mode, I type the word test. I then click on the board canvas to get out of edit mode on the sticky note.
• Finally, I press Ctrl-Z once, which undoes the word “test” and then I press Ctrl-Z again to undo the creation of the sticky note.

And in this test, I add one more word in the sticky note (a third action), and then I use the Undo action in the Miro board which undoes all three actions with three undos.

Have you tried

• disabling any browser extensions?
• Clearing your cache? 
• If you are on a laptop, and currently using an external keyboard, have you tried using the laptop keyboard only?

@Robert Johnson The issue is still persisting after disabling extensions and clearing cache. I unfortunately am not using a laptop but the keyboard seems fine with other boards. The undo button on the left panel works fine but CTRL+Z still undos twice (I’ve tried with a pen and drawing 2 lines and pressing CTRL+Z once removed both lines)

I tried the sticky note too and it removes both the text and the note. I am not sure where the issue may be if it works for you but not with me.

I suddenly am running into this too!

IPAD Pro, Miro app, Touching the CTRL button just does whatever last action i did.

If i last duplicated, touching ctrl duplicates again

if i last hit undo, then every time you press ctrl it undoes.

Ill try to find out where we have support and report it as a bug I guess.

Same issue here on thé iPad app, cmd button is undoing without pressing z. I can’t use any shortcut.

same issue on ipad as above — absolutely strange behavior.
