cant work on full document
There's no sidebar scroll so when you try to add or use pages to pdf, its not possible to work on the whole document. if you use the arrow key to scroll it deselects all the pages you want to change
Thank you for reaching out. Have you tried
2. Select pages by clicking on the checkboxes at the left top corner of the thumbnails. Using arrow keys should not unselect previous selection.
Please let us know if that works for you
