YouTube Monetization disabled and re-enabled!

Like many small time YouTube creators, I also got an email in January 2018 about changes to the YouTube Partner Program (YPP)  regarding changes new threshold of 4,000 hours of watchtime within the past 12 months and 1,000 subscribers. The revenue wasn't much but it was good to get some revenue from the little effort made in creating some videos. Unfortunately, my channel did not meet the subscriber threshold though watch time was alright. So, as per the new rules, monetization was set to be disabled.
