Poor user experience for viewing – Microsoft Word Review

Word refuses to view documents sent via email as a SharePoint link. Open on the link opens the web viewer in Safari with a horrendous rubber band effect when scrolling. Close the tab, and go back to the email, click-hold the link and choose Open in Word. It launches in Word and redirects back to Safari to open there. The Safari banner shows Open in Word, click that, and the same dance back to Safari. MS integration testing gets a fail.
