I’ve also been running into the same problem for the last 2-3 months. On my end it appears to be a process-specific problem. If I cancel the DMT set, copy the remainder to a second DMT set, and run that in a second DMT tab, that second tab will run just fine. The only thing to watch out for is, when DMT freezes it’s waiting for a response to the the next unprocessed row in the list, so don’t copy over that first unprocessed row. Leave DMT open and that ‘canceled’ set will return results on that remaining row eventually.
