Google discontinues Stack PDF Scanner app in September, promotes Google Drive's built-in scanning.

Google is discontinuing its Stack PDF Scanner app in September, encouraging users to switch to Google Drive's built-in document scanning features instead. Stack, developed by Google's Area 120 incubator team, allowed users to scan and organize documents and receipts on their mobile devices. Users who still have the app installed can export their scanned documents to Google Drive before the September shutdown date.
