Hi,

In odoo, the products are available on the right side of your page. please check the below screenshot.

Hope it helps

Same here.  I've noticed this issue just recently and have no idea how to get it back. 

Checkout Overview is shown on mobile device, but not on desktop, so it should be CSS issue. 

My database is on Odoo saas-17.1.

EDIT:

I've also noticed that "Order summary" block is hidden on wide screens, but visible on smaller (like tablets or phones). 

I would post my screenshot, but I can't because I don't have enough karma points.

EDIT2:

Odoo support got back to me also, and I had to hard reset "Checkout page Layout" view.

Apparently I have somehow changed this view and functionality was broken.

This are the instructions if anyone will encounter the same problem:

• activate developer mode,
• --> Go to Settings--> Technical --> Views --> Checkout page Layout --> Gear button --> Compare /Reset --> Hard reset.
