Page formatting lost

We lost the ability to place pictures side by side on one page.
We use pictures as buttons and we used to be able to place them next to each other.

After the WordPress update, we can no longer do that, unless the pictures are very small.
I am confident that we are trying to do something that is on the demo site.

Do you have any suggestions?

Hello there,

Maybe the new Gutenberg editor broke it. You might want to disable it and use classic editor by activating the Classic Editor plugin.
