WhatsApp

[Mups]

I just had a message saying my WhatsApp needed to be updated.
Then it got complicated. 

It asked me whether I wanted it doing to  Google Play Store,  Galaxy Store,  or AK Pure.   
How the 'eck do I know!       I don't consciously use any of them.
In the end I chose  Play Store and it seems to be working alright.

Was that OK do you think?
