We recommend to keep your Instamic's firmware up to date following the procedure below.
Instamic Pro and Basic - Latest version 1.3.2 (Release Note)
Instamic Pro Plus - Latest version 2.0.37 (Release Note)
In order to upgrade your Instamic, you would need to register your device at register.instamic.io (Basic and Pro versions) or register.instamic.io/plus (Pro Plus version) and download the Instamic Firmware Upgrade Application on macOS or Windows.
You can read your Instamic serial number on the back of the unit or on the side of the Instamic's box (it starts with B or P)
The full procedure is explained in the video below.
