OK thank you for the update and if we make anymore progress we can always just ask for an update.
There was some misunderstanding in the meantime. Guild update (members update) is separated from the Progress update. Guild progress is automatically updated for all guilds at wow-heroes. If you want to see faster some boss kill updated for your guild you can find your guild on Progress page, and click on the circle icon at the end of the line of your Guild name (as you can see on the screen shot)
