Genuine question: Would the caching/reindexing have been different between the later beta releases and the final release? Would those incremental beta releases not have triggered the process each time? If not, then this explanation makes sense, though the one thing that doesn’t make sense is that I’m still seeing lower life after a full week.
Regardless, it seems like a nuke and pave is probably in order to see if that corrects the issue.
Sadly, both Home Depot and Target have “marketplaced” their online stores as well, so you have to sort through the garbage just like Amazon.
