It's probably on the line.
It doesn't suggest why there's a problem or confirm that it's a problem with a specific browser. If you did this, it would be a much better answer... But it's certainly on its way there.
But I'm saying that with context. I know that on a technical level Chrome likes to block things it considers suspicious. "Try another browser" isn't always going to be a relevant answer though it might be a good debugging point, which would make it a better comment in those cases.
In this specific case (because somebody's just trying to get something done, with a looming time constraint) suggesting the use of the default browser isn't a bad idea... Just explain why it's likely to work and you'll be well into answer territory.
You could also develop the idea about transferring them to another cloud repo. I don't know how one would do that without first downloading them.
