Firmware update X21200RL released for SanDisk Extreme Pro SSD

I am having problems upgrading my firmware.

I have three SanDisk Extreme Pro 480 GB SSD’s (two in a RAID 0 and one as a boot drive) and use an ASUS X99 Deluxe MB.

I have upgraded my SanDisk Dashboard to 1.3.0.

The top of the dashboard has a yellow exclamation point next to my firmware verion (X21100RL) and says “New version available”

When I click on the “Firmware Update” tab, the window says “The firware is up-to-date”.

When I click on “Check for Updates” the dashboard pops up a new dialogue and shows a progress bar while it checks for updates and then says “There is new firware available for this drive.”  When I click “Ok” on that dialogue it brings me back to the main dashboard dialogue which still says “New version available” at the top and “The firware is up-to-date” in the “Firmware Update” window.

While there appears to be a new firmware available (X21200RL), the Dashboard seems confused claiming there is new firmware available but mine is up to date.  How do I fix this?  Is there anywhere the firmware can be downloaded separately so that I can manually install it?

Thanks
