I have created a multi-tab Google Sheets document. I would like to maintain a certain font and font size each and every time I edit the document or those who have access edit it. For some reason I am having great difficulty as it seems to revert back to Arial 10 often. How can I create a default that will stay put? I am sure that by highlighting all existing data, I can switch it to the default of my choice. it is the new entry material that doesn't seem to want to stick to a default I have chosen. Any support would be great, thanks!
