How do you undo on a Mac iPad m2
Hey @RochardO. Welcome to the forum. 
I’m not familiar with iOS’s version… although it should be similar to Android.
On the iPad, if you have a larger screen… you might have a slightly different UI.
Could you:
- Show a screenshot of what you see?
- What version of the Collabora app are you using?
On Android, Collabora Office 23.05.5, you can do it 3 ways:
Method #1: Undo Icon
After you type something, in the upper-left, you should see an Undo (or Redo) arrow appear:
Method #2: Edit Menu
- Press the 3-line “Hamburger menu”.
- Edit > Undo (or Redo)
Method #3: Repair
This menu is a little more arcane, but you can:
- Press the 3-line “Hamburger menu”.
- Edit > Repair
- (See Method #2 image above.)
In that menu, you can then:
- Select a revision you want to go back to.
- Press “OK”.
That will undo/redo multiple steps at once.
