I complained that book hadn't had a new release email, and they responded it was policy to send one out sometime in 60 days after release.
As far as I know, that email only went to the UK, at day 57.
I follow myself, so I know when the emails come out, and I've not had one.
Personally, I call this a disgrace on Amazon's part, or even deliberate sabotage of launches to force people into AMS, which is a total sick joke now.
I've removed my main Amazon follower's link in my backmatter for recent books, and replaced it with my email list link, and I comment where I can now that Amazon sends followers emails out sometime in 60 days, or never, trying to get people to follow me on Bookbub or my email list instead.
Bookbub are a reliable 3 days after you list your book. Amazon are a sick joke as far as releasing is concerned now.
I still say we need to figure out how to get release announcements to more people, as a forum group.
