I just purchased new and received 2 mp40qd and 2 mp10qd. All but one connected to mobius with no issues, but the final mp10qd will not connect. The W light is on. I've tried the factory reset (), but it's not working. I hold the mode and set buttons, the lights flashes r/w/b, then I hold the mode button until the light flashes red/purple. Then I hold mode and option down, but it never resets, the light continues to flash red/purple. I've verified that all three buttons function normally, but this mp10qd never appears as available on the app to connect. Anyone have an idea?
