WhatsApp Team has been hard at work over the last couple of weeks updating the Beta App. Now again they have pushed an updated to the Windows Phone Beta app bumping the version to 2.16.90.
The team has added an option to Email preview quote a received single message in a group on Windows 10 and Windows 10 Mobile.
Please find the screen shots below of the new update to the beta App. Remember this is a closed beta and the same is not available for download.
