Cannot Type in the Header or Footer Section of Numbers on iMac
I am on my 24" iMac (2021) and cannot type within the header or footer section of Numbers or Pages. I can delete text and paste text into the header/footer, but when I type directly in the field, nothing appears.
This has been a problem since I purchased my Mac in October 2022. I have installed every software update and have uninstalled/re-installed both apps several times. Both apps are updated to the current version.
I do not have this problem on my MacBook Pro - I can type directly in the header/footer to change text.
What can I do/do I need to contact someone specific to diagnose the problem?
