Uploaded builds can't get past "Running"

Hi, when we uploaded our latest build to the dashboard on Tuesday, the tests seemed to get stuck, saying "Running" for a whole day. I assumed the test process had broken, and tried uploading the build again, hoping the restart would fix it, but got the same result. To prove the problem wasn't at our end, I also tried uploading an older build, which had worked before, but got the same result. It seems we can no longer upload anything successfully?

We have had our app released on Oculus early access since June, and we haven't seen this problem before.
