I suddenly noticed that Feed Notifier is not working today (3/27/2020)!!
At first, I thought it's something wrong with my laptop and I uninstalled and reinstalled it; however, that didn't solve the problem.
Then, I also noticed that the link provided by the community article, "How do I set up and use an RSS feed reader?", isn't working, either!
Is there anyone encountering this problem, too?
