Looks like this forum is not monitored by anyone at SanDisk or from outside.
I have still available Version 188.8.131.52 Setup shich detects my SSD.
My SSD is the same like yours, Dashboard 184.108.40.206 did not detect my SSD.
I’m fine with the old version 220.127.116.11 of the dashboard … why should the new one be better? the UI of the new one doesn’t show any difference. I’m quite sure that SanDisk will not fix the compatibility issue of the SSD PLUS 480GB. Maybe because it was sold over a promo (where I bought it online). So keep your 1.4.3 running.
Form their FAQ:
"Why is my drive NOT being detected by the SanDisk SSD Dashboard?
The SSD Dashboard only supports SanDisk brand SSD products. Please ensure the SanDisk SSD and cables are connected properly. You can click on the “Rescan” button to scan the system for connected SanDisk SSDs.
Note: The SSD Dashboard may not support some Enterprise and OEM SSD"
