Here are Twitter's instructions for downloading your data, but there are differences from the instructions which haven't been updated. So here are the updated instructions:
It helps to keep your site clean of plugins that you don't need anymore. If you do not intend on doing anymore Twitter data imports in the near future, deactivate and delete this plugin.
The options are the same as those in the Tweets Tab (above). These are any posts that you have clicked the heart icon on. You may notice that some are just links to Tweets (https://twitter.com/handle/status/#####). Twitter made it very expensive for outsiders to query their API for data, so unfortunately, the contents of those tweets could not be retrieved and displayed here.
If it were possible without paying hefty Twitter API fees, the titles of the Chat Logs would be replaced by the Twitter user names instead of just the sender IDs that you see in the Title column. The Message Count column gives you an indication of how many messages you had in that that DM conversation.
In order to download the Chat Logs (in a compressed zip file), you will need to purchase the Messenger Chat History option. This runs a program that parses your DM records, puts them in easy to read HTML files, and compresses them into a zip file for easy download.
To deter privacy abuse, we are not making chat logs available to import into WordPress. Instead, they will be available as HTML files in a zip file that you can download. You will then be able to open the files on your local computer.
If it were possible without paying hefty Twitter API fees, the titles in the Chat Media column would be replaced by the Twitter user names instead of just the sender IDs that you see. The File Count column gives you an indication of how many photos or videos you had in that that DM conversation.
When you click on a link in the Title column, you'll see a familiar table with the same form options as Tweets (see above). Instead of seeing "Create Post" buttons, you see "Create Gallery" buttons. When click the Create Gallery button, it will upload the pictures or videos in that row and create a post with that media included. A thumbnail preview collage will be created for the blog roll preview of that gallery post if there are multiple images. The "Upload Individual File" button just uploads the individual file to your media library and doesn't create a blog post.
Messenger photos and videos are available as an option to import media into WordPress. You often share these memories directly with your friends, but you don't share them on your timeline. When you upload to WordPress, they aren't turned into posts in a blog, but rather kept in your WordPress media library. You can then share them in blog posts that you then create. Please use discretion and don't abuse this feature.
