Getting the hang of it
I was able to do this today just fine without setting up an account. Not positive what I did, but on a new clients phone, when app was persisting on using a login, I just tapped the "+" button in the upper right hand corner to add the device as usual.
I can confirm this, just tested in a phone which did not had DMSS installed previously. Installed it from play store and could add device without logging in. "Maybe later" was there - as it should.
