The photo captions look fine in the editor but on the actual page they are just aligned left and the same size as actual text.

You can see the photo captions look just like ordinary text. I have also tried forcing align center in the editor and it doesn’t help. I think this may just be a bug in the theme, after googling it looks like a lot of themes have messed up caption handling after the wordpress 5.3 update.
Hey there
You can use this css code to change the style of the caption:
.wp-block-image figcaption {
font-size: 12px;
color: grey;
}
