Issues working with Zepp 1?

Is this version only for Zepp 2?
Im unable to connect my original Zepp 1 with this updated version of the app. The Zepp1 Bluetooth connection is established with our iPad, but does not sync with this updated version of the app.

When I try use use the older Zepp app, I get prompted to update this to new version, so as of now we are unable to sync our swings to our device.
