I need some help. I recently performed a manual update of my Drupal 9 websites to Drupal 10 through Composer. The updated websites are currently in Dev (Test and Live are still Drupal 9). The process has been mostly smooth so far but there is an issue I am not sure how to resolve.
In the Drupal status report, there is a warning that the SameSite cookie attribute is not set. The warning details link to PHP documentation where, as I understand it, there are instructions for how to modify the php.ini file to resolve the warning.
I believe Pantheon customers don’t have access to the php.ini file, so how do we resolve the warning in Drupal 10?
