If you wonder where this real challenge end time is from, you should check out this script too (there are also more screenshots in the comments).

Hi, great script! It has been useful till yesterday! Unfortunately GS changed the page layout so now the script is not working... Is there any chance you will update the script? Thanks a lot man!

Will do 🙂 Just need to get the boost myself and be available to code at that time 😅

Thanks for letting me know 🙏

@Samoiedo77, script updated to v1.1.0 😉

Thanks man! It works like a charm! 🙏🏼
