I am subscribed to the Product & Service Announcements Blogs. On April 27 I received an email with Subject "New post in Blog: Product & Service Announcements." I opened it, expecting to see a product announcement (such as a new version), but instead it just said "27-Apr-2021 | 12:01PM Sunil_GA created Test. Test." I assumed, perhaps incorrectly, that this went out to all (or many) blog subscribers as a test related to the new Community format. But now I see that, since then, there has been at least one new entry in the Blog, and I did not receive it. (I checked my spam folder to ensure it didn't go there.)
I just now unsubscribed then re-subscribed, hoping that will "goose" it. But I thought I'd post here as well in case there are any suggestions or known problems with the emailing of updates from the Product & Service Announcements Blogs. Awhile ago (maybe a year?) I stopped receiving the announcements, and Sunil_GA was helpful in getting them to resume for me.
