Just received S5 Max yesterday and having a nightmare trying to use the Roborock app. When opening 'Enter Robot' it consistently keeps shutting that page down and going back to the previous device page. After maybe 20 times of trying the map page will hold for 10 seconds then close again. If you are quick you can save your edits, but it's not what I expect from something costing this much!
I've updated the firmware, reset, re-installed the app etc. Using Galaxy S4 Mobile with Android 5.0.1
Do I need to send this robot back to the supplier?
