An anonymous reader writes from a report via BetaNews: The notification tray in Android serves a very specific purpose. There's a clue in the name -- and it's nothing to do with advertising. Android user Thom Holwerda was upset this week when Microsoft Office for Android started to spam him with ads for apps he already had installed. There are many questions here, one of which is why is Microsoft ignoring Google's guidelines and using the notification tray to display ads? Thom, from the website OSnews, found that the copy of Word he had installed on his Nexus 6P was spamming him with ads for Excel and Powerpoint -- which he was already using. Mark Wilson from BetaNews contacted Microsoft and they said, "Our team is actively investigating the occurrences of these notifications." After pressing further into the issue, a Microsoft spokesperson said, "Microsoft is deeply committed to ensuring that we maintain the best possible experience for our customers in addition to complying with all applicable policies. We have taken the action to turn off these notifications. This update will be reflected in the coming days."
