HAOS 16.3 Storage Not Expanding on Raspberry Pi 4 (2GB RAM)

Hello everyone,

I am having an issue with a fresh installation of HAOS on a Raspberry Pi 4. Despite using a 32GB SD card, the system only recognizes ~4GB of total storage, and the partition expansion does not seem to occur after the initial boot.

Hardware Details:
Raspberry Pi 4 Model B (2GB RAM version), 32GB MicroSD Card (Detected as 31GB/29.8GiB by Raspberry Pi Imager)

Tried 16.3 (and looking at 17.0.rc1 notes)

I have reformatted and reflashed the card twice using the Raspberry Pi Imager. In both instances, after the “Preparing Home Assistant” screen finishes, I go to Settings > System > Storage and it shows that ~3.9GB out of 3.9GB is used. I therefore can’t install any add-ons.
