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
