Clicking on "Details" in the notifications still starts a new scan if you have clicked on Done in the results.
That simply isn't happening on my installation, Clicking Done doesn't restart the Smart Scan, all it does is take you back to the UI Home Screen, Status tab. This shows the Run Smart Scan button, but it isn't starting a scan for me.
Once you click Done and then open the notifications and click on "Details" it will start a new scan instead of showing the results of the last one.
I chose many permutations and none kicked off the smart scan again.
But I have managed to replicate it this time as it showed Two instances of the smart scan had run and '2' in the Bell notifications. Previously I only had '1' in the Bell notifications, then clicking Details in one of them Kicked of the smart scan, now I have '3' in the Bell notifications.
Clicking done now shows 3 smart scans have run, it now looks like the escalation of the Notifications being displayed described by RejZoR in earlier betas, so it looks like that is back with a vengeance. Now I only have '1' in the Bell notifications but 4 entries for the smart scan.
I draw a line at clicking on details again - so I clicked Dismiss all to get out of this escalation of the Bell notifications saga.
