You do not have any Google Analytics profiles to choose from. Please create new one.

The first time I installed Google Analytics + on a standalone WordPress site, I logged in using the button and my Google account and it presented me with a dropdown where I could select 'All website data' and it worked perfectly.

The second time I installed Google Analytics + on a WordPress Multisite at the network level and network activated it, I again logged in using the button and a different Google account but it didn't present me with the dropdown. Instead, I get the message:

You do not have any Google Analytics profiles to choose from. Please create new one.

'Create a new one' links to the Google Analytics website but I have no idea what is meant by a Google Analytics profile. I looked in the setup guide for this plugin and it doesn't have any troubleshooting or error messages.

What do I need to do to configure this plugin for my Multisite please?
