The histogram 'Cellular.ActivationRetry' is present in Chromium source code
but does not appear in histograms.xml. This means that data is collected for
the histogram but nothing useful is done with it.

The histogram was defined in
chrome/browser/chromeos/mobile/mobile_activator.cc at line 570.

https://cs.chromium.org/chromium/src/chrome/browser/chromeos/mobile/mobile_activator.cc?l=570

It may have moved by the time you read this.

Please remove the histogram 'Cellular.ActivationRetry' from the source code.
If it was very recently added, it may be worth adding it to histograms.xml
instead, but probably not.

This bug was automatically assigned based on git blame information. If you
are not the correct assignee for this bug, please delete the histogram
anyway.
