When you run the script manually, does it throw any error or it just silently does nothing?
In general debugging 5 lines of code via a forum with a round-trip time of several hours is a bad idea. So you if you want me to assist, follow the suggestion in this post or you can just post your phone number or e-mail address here and delete it once I send you a message. A hint - “plus four four” is more robot-proof than “+44”. Bear in mind that the message may stay here for some hours - the e-mail notifications aren’t fast, or even reliable, these days, and also my time zone is not the same as yours.
