No, the Amazon notice by Ridan is undated, and an unrelated third party posted about it on Goodreads on the 31st of August. So it could be that Ridan is lying, but equally it could be that Ridan posted about it on Amazon before June, the author submitted the manuscript in June, and the notice remains on Amazon where the third party spotted it on the 31st. In which case nobody is lying.
Ah, I see. But that doesn't change the fact that Ridan publically stated that it was awaiting a manuscript from an author, and I still contend that that is extremely unprofessional. That's simply not public-facing information.
