Occasionally in the past, and consistently the past few days, my codecov reports do not show the line highlighting (red/green) for covered/missing lines.
Steps to Reproduce
These are reports submitted by jobs on Travis and Appveyor for the topic/R branch (see .travis.yml and .appveyor.yml here).
Expected behavior: The report shows missing lines in red and covered lines in green.
Actual behavior: All of the lines are white.
Flakiness? This used to only occur every few weeks, now it is happening for every job, usually after more than one report has been submitted. Is there a limit on the number of reports?
