Can't type in "Signature" form field
I'm filling a tourist visa application.
I can't type where it says "Signature". It will let me type everywhere except there.
Using Windows 10. My Acrobat version is 2019.012.20035
The form http://www.cic.gc.ca/english/pdf/kits/forms/IMM5707E.PDF
It should be opened with Acrobat cause it's protected. This is their june 2019 version.
Any ideas? Thanks.
