The blocks and pages which were created before upgrading to Magento 2.2.1 do not update the "Modified" date in the admin. The contents are updated, but it appears only the date modified is not changed.
Its sounds silly, but i like to sort my modified date for pages and blocks and this has made it so that is no longer a possibility.
I have tried reindexing, update, compile, deploy many, many times without effect.
It also seem to be affecting products "updated at" settings as well. I am guessing this is SQL related, but have no idea where to begin to address this issue.
Any assistance would be appreciated.
