Crashes file after adding new page – PDF Max Pre - The PDF Expert Review

So far the app is good but this app need to fix to things. First, when I add a text into free text, the first line "which has to stay where I put" jumps up. Second, when I add new page to my note file then I come back after looking something from the other PDFs file, my note PDF file crashes and I cannot open too.
