Paid for the "PRO" version but nothing changes

Paid for the "PRO" version but nothing change from the free version! Pro features supposed to be that the devices connect in the background so I wont need the app open to connect to the devices.
Nope! Doesnt connect!
And worst of all, its asking to pay ¥480 again!!!! Are you kidding me???
