I've got a sneaking suspicion about what's going on here.
Has there been a test for people who do not use OneDrive at all?
I fired up the new MS Photos app, and the first thing it does is offer to sell you space on OneDrive. This appears to be the change driving the new app, AFAICT. Sure, there's a few other features, but the big one appears to be cloud integration. And sale of cloud based services.
I do not use the MS Cloud. Never have, probably never will.
A suspect that at some point, there is a virtual function call or function switch that's being made to determine certain parameters for one's OneDrive/MS Cloud utilization.
So - anybody else here having this problem who DOES use/pay for MS OneDrive?
