I have had the 4 head coral box wifi doser for well over a year. I have had no problems with connection until this week. I originally had it set up through my wifi and could normally connect no problem. It's been almost two weeks since logging in to change anything, and this week when I tried the unit would not populate in the app. So I ran my own trouble shooting after a while, reset the wifi with no luck, reset the unit itself with no luck. The only thing that has changed in this time is I upgraded to the iPhone 11 from the 8 plus. I still have both phones and neither would connect so I don't believe that is the issue. I am able to connect to it's own "Dosing" wifi but when I go to the app it still does not populate. I have removed all other wifi connections I normally use and turned off my cellular data to make sure that the phone is only communicating with the dosing unit. Attached is a screen shot of the "advance info" screen that their website says to do. I have sent this directly to them as well and received a lackluster response that was no help. Is there any additional help you may be able to provide? As of now my dosing unit is useless without being able to connect and change any settings.
