Gallery missing on Portrait smartphone view

I’m trying to create a gallery and have added it in PC view. When I switch to portrait mobile view the gallery doesn’t show up. I have quite a bit of clutter so it’s possible it’s hidden behind something but I’ve tried moving loads of elements to check and also reight clicked almost everywhere to see if it appears in the “select” menu.
Do galleries work in Portrait phone mode and if so, is there a nice way to find it?

Yes galleries work on all devices. You can select the gallery on the desktop view and switch device, the gallery will remain selected, so you can see where it is.

Thanks Duncan. That worked perfectly.
