doc.replace_text doesn't work

[OlekRia]

Here is a file for test: https://www.uscis.gov/system/files_force/files/form/i-9-paper-version.pdf?download=1 I tried to change it using replace_text. Unfortunately, it doesn't work. Advice needed.

I suspect, because of version 1.6

I have the same problem - it doesn't replace text. All text disappears from page. :( I used the same length text.
