Wont do setup

• 

As you can see when clicking init map the floor it's saying tech issues this is the 2nd vacuum this is happening on. What's going on

i’d try logging out and back into the dreame app, reinstalling it, and doing a full reset on the vacuum then setting it up again on a stable 2.4ghz wifi network. also make sure location permissions and bluetooth are enabled during setup since those can affect mapping.

Hello,

You can try reinstalling the app, restarting your device, or restoring it to factory settings.

If the problem persists, please provide your device's serial number (SN) so we can better address the issue.

Also if possible try a different phone.

Did you manage to resolve it?
