Wrong profile pictures and always the same thumbnail in rooms.

In the overview, favorites, persons and rooms, the same profile image is displayed for different rooms and persons. Furthermore, in a room always the same thumbnail image is displayed with different images (and videos). Only when you enlarge the picture you see the right picture. IOS 11 on iPad and iPhone.

Reproduce the issue on iOS 11 across the overview, favorites, persons, and rooms screens, including room images and videos. Trace the image and thumbnail loading paths from those entry points; done means distinct profile and room media thumbnails display correctly without requiring enlargement.
