It doesn’t bother me when an author updates at all but as long as there is some communication that they haven’t abandon a story. I only say this there is one author loved her stories so much use to update regularly then suddenly nothing no communication on Instagram nothing.
But there is one who takes that long to update I don’t bother reading any of their stories until there completed.
But I do believe stories should show when it was last updated so readers won’t waste passes on a story that won’t be completed.
