Exporting to PDF

Hi

I have a report that is two matrix tables next to each other and is very wide. On the power BI desktop if I export to PDF it fits both tables to 1 page. However if I do this in the online service it cuts off half of the second table. I have tried in chrome and internet explorer but get the same output. The page size in desktop is custom and width 4961 by height 3508. I want to be able to export to PDF on the service and have the tables appear on one page. ANy help would be appreciated,

many thanks
