Hey James. Thanks for sharing the story so far.
I noticed a previous post of yours from April

You were on an extension of stay that was valid until December 2019, but you stated that your WP got cancelled, therefore it made the extension invalid.
That thread was closed, so no further updates on the situation.
My question is: between April and the time you left to the UK, did you continue to stay on that extension of stay or left the country on the date of the WP being cancelled and continued with tourist visas / visa exempt on the old passport?
