devtools::test_coverage() reports coverage but covr::package_coverage() &report() reports 0.00% coverage

Good morning, I have created a fairly new package and I am currently cleaning it up. As part of this process I am utilizing covr to manage unit testing. For some reason devtools::package_coverage() seems to accurately report unit test coverage but covr::package_coverage() and covr::report() reports 0.00% coverage. This is confusing to me since the devtools::test_coverage() documentation states that it is simply a wrapper around covr::package_coverage() and covr::report(). My package, for reprex, can be found here.

All of your tests have testthat::skip_on_cran() in them. covr::package_coverage() runs the tests as in the exact same way that CRAN does, e.g. it has no knowledge of devtools or testthat. In particular it does not set the NOT_CRAN environment variable, which is how testthat / devtools denotes if a test is running 'on CRAN' or not.

run Sys.setenv(NOT_CRAN = "true") before calling covr::package_coverage() or covr::report() if you want these tests to run.
