Hi, is anyone using the above dosing pump? I am trying to do a flow calibration and when I enter the flow calibration results and click complete, the app spinning circle non stop. Phone is android and app is the latest. Connection to the doser via the internet is good. I restarted my phone and also restarted the app the it's the same. I tried doing manual dose for 5ml on the app but the cylinder measures 5.2ml. So I tried flow calibration but the app just spin busy each them when I click complete.
