installed my rachio 3 yesterday. Although it seemingly was working fine I twice had the application lock up and was forced to go to the control box to turn off the water. This morning the phone app (android) locked up at startup (blue screen and logo). I tried to force a stop but got a “server not reachable” message. So I had to uninstall and reinstall to get it working again. Went inside to change some settings using Win 10 desktop computer. Have seen it lock up three times (so far) with the screen going completely blank. A screen refresh brought it back but at least one time took 15-20 seconds. A forth lock up yielded a “error loading data” message with the blue circle of death on the screen. I had to close the window and log back in. I can see that if the Rachio server is critical to making this thing work. hope this doesn’t continue. as a new user, should I be concerned? FYI, I have very good connectivity to my wifi network with both my phone and the rachio.
FYI: my phone is an Samsung G7, Android 8.kernal 03.18.71. My desktop is HP Envy, Win 10 v1803
