I bought the S4 from Amazon a couple of weeks ago, ~ December 22, 2019, and I don't know which Android app I should be using. I tried the Roborock first with limited success then Mi Home, again with limited success, and now I'm back to Roborock. I believe I have the latest robot SW (01.03.06) and I just downloaded the current Roborock from the Android Play Store a week ago. The robot just finished vacuuming the house and I believe it did a good job However, it is not displaying a map, just the "Map loading" message. I don't know how to use some of the features without the map. Which app should I be using? If it's the play store Roborock, then how do I get it to display the map.
