Facebook introduced "Reactions" on its Android, iOS, and Facebook.com a couple of weeks ago, but the Windows and Windows Phone applications were left out from the initial rollout. Now, it seems that the company has finally started testing Reactions in the internal beta of the Windows 10 version of the application.
Even though the Facebook Beta app for Windows 10 from Microsoft was updated twice since the rollout began, the feature wasn"t included in these builds. According to a Redditor, the latest update to the private beta of Facebook for Windows 10 developed by the company itself includes the various Reactions, which appear after long clicking on the Like button. Users who do not have access to the testing version of the app will need to wait a bit longer until the feature is incorporated in the regular builds by Facebook.
The Facebook version of Facebook Beta for Windows 10 can be availed from the Windows Store link provided below, but only those who have received an invite for testing it can log into the app. It is still unclear when or if Windows Phone 8.1 users will get the feature.
