Really dear friend @ mars9 I do not know what to answer, to me it is happening the same, my income levels have decreased by more than 50% as well as the votes, I have between 60 and 100 votes less for each post. I can not find any logical explanation.
The only thing I can tell you is that you have to wait hata on the 20th and see what happens next
Thank you so much for visiting my work
