My apologies in advance--

When I first set up Scrivener it was using the UK spellings (which suits my current project). It now is using US spellings and I don’t know why, or how to change it back. I looked in preferences and couldn’t find it.

Assistance, please? Thank you!

I looked for it and it really is pretty well hidden. But here it is.
Edit/Spelling/Show Spelling & Grammar
Then you’ll be able to select the language you need.

Thank you! I don’t know how it changed (unless it was with the upgrade, which makes no sense because in the past the UK was the default) but I’ve now changed it back.
