Hello Jim,
Thank you for your advice.
Firstly, the actual grid is gone. The elements, mainly text but also videos, are there, but - again - the underlaying grid is gone.
I tried closing and restarting, nothing changed.
When you write “stepping back”, do you mean the “Undo” button, or something else?
We might be in different time zones, it´s 8.15 am here now
