I gave it some time, and for 12557773c8f9e6632fb240f1bce8e07a74c50208 the AppVeyor jobs report that they uploaded the coverage information, and if I go to the reported URL manually, it is indeed there. However, the CI tickmark still hasn’t been updated.
The next commit in the branch, 6d98573d919976e1f2b93143e87b1d46a135cf3e, has the tickmark updated.
Honestly it isn’t much of a problem, I just found it curious.
Sorry @drazisil we were busy with release activities until now. Our project does not use a codecov.yml because the default one suffices so far. But if this is required then we will add one. Please advise
No worries!
Yes, in this case it is needed.
Yes it works! Wonderful 
Just one more question, how long does it take for the code coverage badge to show a percentage rather than “unknown”?
Never mind. I figured it out myself. Thanks for looking into this 
Not sure if this is the same problem, but codecov not showing report in my recent PR again. This is the recent upload from appveyor:
https://ci.appveyor.com/project/msphpsql/msphpsql/builds/32641850/job/ppl9obcilorhoa2y
I did notice it’s uploading report to View reports at https://codecov.io/github/microsoft/msphpsql/commit/4925e60e088033eba5454f967eb2c4b9bcedff3f
But this is where I found the report for this commit:
Please advise. Thanks!
