Office Insiders on iOS are getting a handful of new capabilities for the unified Office app as well as PowerPoint with the latest updates to the apps, which bring them to version 2.49. The unified Office mobile app has the most news, starting with the ability to merge multiple PDF files, either those stored on your phone or in the cloud. You can merge PDFs from the Actions menu, from the Most Recently Used list through the triple-dot button, or by selecting Merge from the menu while a PDF file is open.
Another addition to the Office app is a new Shared view on the home screen, so you can more quickly find files that were shared with you but that are saved on someone else's account. This change also recently rolled out to the Office app on Android, though Microsoft hasn't made any mention of it in its changelogs. Finally, there's a new Read mode, which is now the default when opening documents. The goal is to prevent accidental changes to documents if you're just trying to read them on the go.
As for PowerPoint, there's only one new feature, and that's the ability to select multiple slides in a presentation. You can tap and hold on the first slide you want to select, then tap all the subsequent ones.
These Insider builds are usually previews of next month's update for general users, so if you don't want to join the preview program, you can just wait a little longer to try them out. Otherwise, you can sign up for the previews using the TestFlight app, assuming there's still space for you, since TestFlight programs are limited to 10,000 testers.
