When you click undo, the redo button appears in the undo button place.
When we want to click several times to undo we have to click the undo button and then click further to the left, where the button appears next
Would be nice if the undo button started more to the left and redo just hid rather than collapse.
I’ve ran into that before - I would propose grey-out/disable the redo button instead of hiding it as a fix
