Hi Gary,
Thank you for posting your question in our forum. However, our team only provides support for AdWords / Google Ads API related concerns only. If you are referring to this recent
blog post, and if you are currently maintaining an application which uses or stores AdWords entity IDs (as specified in the post), then I would recommend that you apply the changes mentioned in the blog to avoid any issues.
Best regards,
Peter
Google Ads API Team
