I am having the same problem with our open source project. I have verified that the reports are uploaded successfully and can see it on the Codecov portal. Rerunning the pipeline no matter how many does not help.
I have also remove and readded the repo and that doesn’t help either codecov: testing codecov fix by mydiemho · Pull Request #857 · microsoft/VoTT · GitHub
PS. I have to disable the codecov commit status to unblock our PRs so you won’t see it in the status check
