yes the app is currently broken but I recently saw the firmware update changelog, it had something related to the cloud and I think it's for the app, you can update the firmware using flux studio go to : machine > yourMachine > update firmware > machine firmware and toolHead firmware, I don't think it's necessary to update the toolHead firmware but I recommend you update it. I'm still not sure the flux will work after the update with the flux app as I didn't update my firmware.... yet... will do it now, please report back if the firmware update solved the app connectivity problem, if not then go to this topic and reply to proclaim about your problem on this post http://forum.flux3dp.com/t/flux-studio-0-7-8-change-log/2527/12, hope this helps! EDIT: oh and download the firmware files from here : www.flux3dp.com/downloads. Good luck! EDIT: it should give you the option of connecting the machine to your wifi network because it did give me that option on my first setup, oh and the connecting by both methods thing is pretty easy, you just have to go to machines > notTheUsbProfileOfYourFluxDelta > set as default, thats it! now it will use the wifi profile of your machine as the default one , hope this helps again! . EDIT: just updated the firmware and the app connection still doesn't work, you should update the firmware anyway.
