Signing in to Google Play
... so I don't lose my progress if there's a power cut, which we have unexpectedly because of cows. (Honest.) Following instructions, which only go so far as 'sign in', I get the page below, then ...
Google Play, if I remember correctly, the first prompt is for your email account associated with your profile. For you, one choice it seems, Aunty Social
Then it will ask you to choose the correct identity (why there is a first false identity I can not fathom at all) which is the one with all your plants and resources !!!!
The final screen will prompt about user name (profile) and here is where you can type in the correct one, create a new one, or just hit ENTER.
Hit ENTER and you then have to use Google Play button again when the main screen shows up in order to retrieve your playing profile ! (user name)
edit: hopefully this explanation makes sense :-)
