We recently release SmartOffice 2.3.21 for iOS, new features are:
• Support for opening password protected docx/xlsx/pptx documents (if you edit a document if will be saved without password protection - this will be improved in a later release)
• Switch to new Google Drive API (Google will be disabling the current API SmartOffice uses soon. This means you will have to login again, sorry.)
• Improvements to PDF rendering and handling of MSWord files
• Various crash fixes
We’re aware of an issue with Chinese text in some cases, the fix for this is coming in the next release.
