Frequently Asked Questions
Why does a black box appear over my signature when I save a PDF on my iPad?
This rendering issue is often caused by PDF compatibility conflicts or bugs in outdated app versions. Try updating the application or flattening the signature document before saving it.
Will I lose my saved signatures if I reinstall the Adobe app?
Yes, uninstalling the app usually removes locally stored signatures and profile data. You will need to draw and save your signature again the next time you open the freshly installed app.
Can a very large PDF file cause the signature app to crash?
Yes, extremely large PDF files or documents containing complex interactive forms consume significant memory, which can lead to application crashes on iPads with limited RAM available.
