Signature window not popping up
I have a case where we have used Adobe Sign to send a very simple pdf to a user for signature (older, not-tech savy, Mac user). When clicking the signature box, nothing is happening. No signature window is popping up. Have tested sending to other users (both mac and windows) w/out issue. Any ideas? My guess is possibly a very old/out of date Mac that for some reason is causing issues. Anything to confirm/reject my guess is appreciated.
