JetPack Subscription Button is Now Working

Hi there. I’ve been using Jetpack for some years and I had many subscribers by using Jetpack newsletters. Unfortunately, a couple of days ago, probably after updating Jetpack, that widget stopped and not working anymore. I get this message in widgets “Your site doesn’t include support for the “jetpack/subscriptions” block. You can leave this block intact or remove it entirely.” Any ideas? How can I fix it? Thanks!
