People who open the app now see the following message:
After today, you will no longer see any new articles on this app. But it's not a goodbye because there are still other ways to keep in touch. You can find us on Facebook, Twitter, and Instagram. And remember to subscribe to our newsletters to receive latest information, tips and offers from Microsoft Lumia in the future.
Nokia first launched the app under the Nokia Care name. In 2014, after Microsoft bought Nokia's Devices and Services division, it changed the app's name to Lumia Help+Tips. Earlier in 2016, the app's name change again to Lumia Highlights.
This latest development shows yet another move by Microsoft to cut down publicity for its Lumia phones. Earlier this year, it shut down the majority of its official Lumia social media accounts.
Thanks to Keath and Daniel for the tips!
