WD Photos App for Android - Created Public Share sub-folder based on GMAIL

I just downloaded WD Photos App, and wanted to synch with a specific share on my MyCloud drive. Instead of prompting me for a destiation, WD Photos automagically created a new share, based on my GMail account - I never entered anything.  Some questions:

1). Is automatically creating a wdmycloud\Public[gmail_acct] share default behavior? 

2). What would have happened if I didin’t have a GMail account?

3). Is there any way to change the destination share?

I might have missed something, but if this is standard behavor, it’s a pretty weak app. 


WD Photos will upload to the public folder. The destination share cannot be changed.
