@Saphyel we need this field, why is it being removed? this built by @wagg-matt as part of the scheduling work AFAIK

[pvhee]

@Saphyel not sure what is the direction of this PR? Can you please explain this?

[Saphyel]

@pvhee fix the import. I updated the description
if the field field.field.node.article.publishing_date is necessary why is commented out in cr_article.info.yml @wagg-matt (and why there is already another publish_date)? that field is causing troubles and not following the standard of "modulename_whatever" happy to resurrect it if is needed by other module

[wagg-matt]

@Saphyel @pvhee I had to remove publish date to replace it with publishing date, first time exporting and did most of this manually so may not be 100% correct.

The original publish date field was todays date and would have just been confusing to have that and the scheduled updates publishing date.....clear as mud?
