February 9, 2023 Update:
Thank you for your inquiry related to our bulk-editing features. Unfortunately, our card and end-screen related features are no longer available due to technological changes in the industry. We are doing everything possible to provide our users with the best available services and exciting, new tools are continuously being developed.
We sincerely apologize for the inconvenience. We know these changes impact the way you use TubeBuddy. The features Bulk Find, Replace & Append, and Bulk Thumbnail Overlays are still available for your use. Thank you for your patience as we continue to address these changes and preserve the best experience in TubeBuddy.
January 2023:
We are aware of a recent issue with the card and end screen update features (including bulk updates) returning an 'invalid argument' error message. Our Dev Team is working on these issues. We sincerely apologize for the inconvenience.
We'll post updates in this article as we learn more!
