Ah looks like I'm not alone with this issue. Maybe a holidays thing if they have to manually adjust something, though I would have thought the process would be automated. Or maybe they have had a policy change, though if that is true I can see no announcement/email advising of same.
Good to know it wasn't just me! I assumed it was a policy change when they started pushing the new app from the old client as incentive to "upgrade" :/ Hope it's not because, yeah, I use the "update all" functionailty a lot. Still don't know why that's a "premium" feature
