The content is clearly understandable despite those few typos. Don't worry about it too much.

I live and work in England, and my spelling has never been an issue to find work. Ok my vocabulary is still limited, but I learn everyday. I might do some very strong grammatical mistakes and typos, but usually people just correct them I try to avoid doing them twice. All my post are now checked in Grammarly, to avoid those situations, but I know the process is not 100% accurate, but it's still better than nothing. I've just copy pasted the text in Google Docs and you're right there are few typos. I've going to correct them now.

Don't worry about it. It was perfectly understandable and a very informative post.

Thanks!
