(De-)Archiving issues. Troubleshooting didn't work

Hey @Mattaro, this isn't ideal, agreed. For very old archived conversations, ChatGPT may not be able to reliably load the unarchived conversations in the UI.

The export is designed to include your chat history, so you can review the exported files, copy or save the content you need, and then clean up any conversations that remain accessible in the product - Avinash
