Thanks for the comment. It’s my first article on Medium (I’m not a writer but feel I have some interesting views that people might want to read). I did proof read it a few times and missed the typos!
I also assumed Safari would have highlighted anything spelt incorrectly but obviously not. It seems to behave strangely with Medium, but I’ve pasted the article into Grammarly to hopefully pick up everything.
I’ve updated the article with (hopefully) all the typos fixed and some grammatical corrections.
