I just updated my iPhone 7 to iOS 11.4 and this seems to cause some issues to my Photos.app library. I'm using iCloud Photo library and right now when I checked the amount of Photos in the "Albums" view of Photos.app on iOS the amount of pictures is way lower.
Also some old pictures are suddenly showing up mixed in with the last photos I took a few hours ago.
When I check "Photos" it tells me "Uploading 7.xxx Items" at the bottom.
Does anyone have a clue what's going on there and how to fix it?
