Updating MM firmware

Hi. This is not working for me. I downloaded the iOS app today, but I can’t see where it says what app version number I have.

I power MM down, close iOS app, power MM on, get the BT light flashing, lacuna the iOS app, press hamburger button, select Update Firmware, and then it just takes me back to the “My First Configuration” start page.

One of the posters above says his app says “cadence-12” at the bottom. Mine does not say anything like that.

I’ve tried a few times now.

Any hints?
