1939 register - redacted entries

[LizzieL]

I know that FindMyPast is updating (unredacting - if that is a proper word) the entries on the 1939 register on their site as they have confirmation that the redacted information has passed away or if they are over 100. Today I was looking up a family on Ancestry, where one child was redacted. Which I found odd since her birthday was 22 October 1920. She is shown, as expected on FindMyPast, the writing is very clear, impossible to mistake 1920 for anything else.
Is Ancestry not updating their 1939 register?

I believe that FindMyPast update regularly and as requested with proof of death, but Ancestry only update once a year. 

From the National Archives

"The version of the 1939 Register on Ancestry.co.uk will be updated annually to show the records that have been opened during the past year."

Yes FindmyPast as the digital dataset compiler and operator unredacts the relevant entries then every so often send the National Archives the updated dataset. The National Archives in turn sends copies of the update to their licencees.
