'Slack Beta' development abandoned
(All About Windows Phone)

A year ago, I reviewed Slack (Beta), a WinRT `universal` app for Windows Phone 8.1 and above - it worked, but wasn`t exactly optimised for anything, wasn`t a true Windows 10 app, and showed a distinct lack of care and attention. The hope was that Slack would continue development, but this never happened in terms of functionality and now the company says that future development is very definitely over.
