That is what I am getting too. I guess I just preferred the next image option. That then seemed to stop the current image being static for days.
The set of 4 pictures changes now usually once a day.
Originally, they were changing way too often every 15 minutes, that was annoying and distracting while in the middle of working, it was causing the working window to lose focus and go in the background. 😝🤬
Hopefully they fixed that problem. 😎
