I use scannable for signature pages on contracts and have never had an issue until recently. Scans are great, emails perfectly with white backgrounds and even pastes into the existing pdf file no problem. But as soon as I save the file, the pasted in Scannable scanned page turns purpled. I have used my husband's phone and his scanned pages turn green. I've re-installed to no avail, and the support for Scannable seems non-existent. I use an iPhone 6 and a MacBook Pro, and have always done all my pdfs through Preview. Thanks for any insight.
