I do not use the tab choices to see my pictures. I go into Shared Pictures, I have them separated into folders for iPhone and iPad , open a folder and can see all content in each folder. Nothing is missing.
Follow below steps:
- Make sure you have a stable connection and iCloud backup is on
- Make enough free space on iCloud
- Reset network settings
- Reset your iCloud account
- Restart or Reset your phone
I hope this solves your problem.
In the end, the missing thumbnails in the sheet “Photos/view by date” are recovered after rebuilding content database.
I have tried WD Power off/on.
I have tried Cloud service off/on.
Both don’t work.
If you ever feel that some pictures are missing, please try “content database rebuild”.
