SOLVED:: As per the post below Remote assistance is not yet working.
I am having problems enabling remote assistance under 0810 alpha. I have tried via webadmin and advanced-Remote access. Web admin goes fairly unresponsive when i select enable remote assistance (with or without port 22 ticked).
If i go in via ui2 then clicking enable remote assistance then the ui changes to "One moment" but never enables remote assistance.
I have made sure i have port forwarding on my router, and have even tried the above with the firewall on both mce and my router switched off with no changes. Am i missing something?
EDIT: Just to confirm i have used my laptop to nmap port 22 and it is defiantly open.
