unable to type text in Keynote theme

Hi

Since yesterday July 25, I find myself unable to enter text in any text box in Keynote. I cannot enter text in a "placeholder" type of text box where it says "Double click to edit".. I cannot enter text into a text box defined in the "Appearance" part of the format pane on the right.

On the iPads, keyboard doesn't come up.

The only way to type is to add the slide as it is on the presentation.

Impossible on the "edit slide layout mode" as it used to be.

This is happening in ALL my apple devices, iPad Pro, iPad Air, Mac mini, Macbook ....resetting or else won't work.

HELP! :)

Thank you.
