The new version of Max2Play is ready for download and can also be updated to on any existing system. It includes a fix for the Zero W to work flawlessly amongst other things.
When connecting your Zero W via WPS with a freshly burnt image, make sure to boot the Pi first and start the WPS search second. The Zero W takes a little more time to boot, expand the filesystem and connect via WPS. If you are not connected by the first WPS search of your router, please start a new scan and the Zero W should be detected.
