18 November 2023 Similarity stopped working in all accounts and versions. I have the same issues that started this week, I posted an error to Help Support in Word, no reply yet. I have a school account, and all versions desktop 2016, and 365 have the same error message.
It started as I was marking in Teams Assignments using Word. I activated Turnitin for an overdue Teams assignment, using settings option to apply Turnitin to all assignments, messages displayed below all students' files displaying "Turnitin pending". I waited and waited, nothing. I returned to Similarity in Teams Word, and ran Similarity. It was pending for some time and then displayed the error message.
I copied text into Word 365 online account, same again, same error message. Tried my Word 2016 also the same, Similarity runs, says pending, then displays the error "something went wrong try again". All versions have stopped running Similarity. Any news anyone?
