Why does Structure's Firmware Updater not work?
With the release of the newly-rebuilt Structure app, users can upgrade their Structure Sensor (Mark II) from 0.9.8 to 0.9.9 and beyond.
When upgrading, please be sure to begin the process within the first minute of launching the app. Otherwise, the sensor may run out of memory and be unable to finish the upgrade process.
Please also be sure to charge your sensor prior to upgrading the firmware.
If your firmware screen stays in the above state for more than two minutes, please force close the app, briefly disconnect your sensor, reconnect it, and try upgrading again immediately after opening your app.
Do not disconnect your sensor until the upgrade has completed.
