This is an audio demonstration of "DocuSign," an app used for electronically signing documents.
"DocuSign" is not accessible, when it comes to both creating the signature or the initials with Talkback on.
Talkback must be suspended in order for one to be able to draw his or her signature or print his or her initials.
The part that has the most accessibility problem, is the fact that the document that needs to be signed, whether it is an existing document that is imported for a signature, or one that is captured using the "capture mode," resulting in taking a picture of the document, is inaccessible.
The screen reader isn't able to read the document, thus, it is impossible to find the spot on the document that needs the signature or the initial.
The Dev should be contacted and see if this problem can be fixed.
