Hello again lock042.
I did now see those menus items, and tried the solving feature.
Since I do not directly save my images in the .fits format, I could not get a solve.
I tried several of my images, but none will solve.
Is the .fits the only format that works with Siril's plate solving algorithms?
Interestingly, the website "nova.astrometry.com" can solve many of my images in several formats.
