    Early this month I purchased Lumia 640 XL. It runs great with WP 8.1. ThenI have installed Windows Mobile 10 Tech ( this was on June 7 i Installed, not sure of build version). Prev . After upgrade I have encountered many issues such as:
    1. Default Email client (outlook) stopped working. Cannot configure
    2. WiFi signal receiving has dropped down- was very good with Windows 8.1

    So I restored WP 8.1. It works great again.

    Does anyone else has encountered similar issues.

    Thanks for help
