When I airdrop a Goodnotes 6 file or page to someone using GoodNotes 5, it crashes down and the folder to which the page has been added can‘t be opened any more. Especially at school this is a big problem - all our pupils use GoodNotes 5, some teacher use Goodnotes 6. And now I can only airdrop pdf files, which does not allow the children to move around bits of text. Please make the two versions compatible.
