I own the Ultra Plus SDSSDHP-256G. The current firmware on it is X211200, and the new firmware is X2316RL.
When I select the “Check for Updates” button in the software, it states that my firmware of X211200 is up to date, but that is incorrect. The new firmware is X2316RL. Perhaps a bug in your software?
I can do the manual update, but it’s a bit inconvenient since you, SanDisk, probably spent a good deal of money to develop this SSD Dashboard software. Maybe you guys can fix this bug?
In the meantime, I’ll try to do an update via windows boot.
