WhatsApp beta has been updated to version 2.17.90 for Windows Mobile and Windows Phone. This update includes minor bug fixes, performance improvements, and some new features.
First, this update brings the emojis available in Windows phones on par with Andriod and iOS. The emojis present in Android and iOS and missing in Windows have been added to the app.
Next, they have built an in-app video player inside the app. Now for the videos received or sent, you wouldn’t be using the legacy video player. All videos will be played in the WhatsApp itself.
