I am writing my end of studies project report on latex (overleaf). I had to use A3 size pages to insert large size charts and tables but had two issues:
1 / The numbering of the A3 page is no longer displayed (knowing that I use the "plain" style) because I had to change the page margins (to display the graphic centered in the middle). How could I display it at the bottom center?
2 / The numbering of the A4 page which directly follows the A3 page has moved to the middle of the page What to do, please?
