I had the maps working great, then I tried to divide a room. The app (up to date) locked up, so I restarted it. When it restarted the different zones were gone. So now I am trying to go to Settings, Manage Maps, from here my map is displayed. I click Edit, Edit Room, wait for the map to load. I now have 3 buttons at the bottom, Merge, Divide, Name. All of them do nothing. The Re-Split Rooms button at the top also does nothing.
Any suggestions? I have don everything short of deleting the app.
Update. I cleared the cache on the app, restarted the device. I then re-mapped the floor by letting the vacuum do its thing. I can now divide the rooms, but I had a terrible time doing so. It took forever and would not divide them like they were previously divided. I am guessing an app update introduced these issues?
In this case, you can email support@roborock.com and they can send you a video to show how to divide rooms. Also you can send them some pictures to show how you want to divide it.
