Hello @Georgi 

Second error indicates that you need to change your sentence, because the browser was trying to send the same request in a short period of time which triggered the error. Change the sentence a bit and try again.

Thank you, Nikola, for your suggestion. My current take is as follows: the first error somehow remembered my answer and later rejected it, thinking it was a duplicate. It was not a single sentence, but rather three paragraphs and a five-item bullet list. My idea was to wait for several days, and it passed a couple of minutes ago with no error message this time. So my response is now posted, unchanged. I hope this observation helps. Wishing everyone a beautiful day!
