I've just installed iOS 10 Public Beta 7 on my iPad Pro (9.7 inch). If you select a single photo in the photos app, you get a button on the share sheet 'Add to iCoud Drive', but if you select multiple photos, the 'Add to iCloud Drive' button disappears from the share sheet. Am I doing something wrong? Or is this a known bug? Or a design choice? I want to upload my naughty photos to iCloud Drive so they don't appear within my photos app. Doing it one at a time will take forever.
