Exactly as described here for 13.21beta and 13.24beta, I am missing the background pictures of the morning report after updating to firmware 13.24stable (at least 13.24 is shown to me as firmware):
Since my watch was exchanged and I updated directly to the beta firmware 13.24 (without an intermediate step) and then to 13.24 stable, I no longer see the pictures. They were present on my previous watch with 13.21.
Here is a photo from last Sunday:
Other photos can be found (not only by me) in the linked threads.
