I'm integrating Dropbox with Fastlane CI/CD to upload the artifacts. I'm using the fastlane plugin "publish_dropbox".
It does not upload the files to the destination Dropbox folder.
It sounds like you're using a third party library for connecting to Dropbox. Since that's made by a third party, we can't provide any support for the library itself. If you're having any trouble with the library, I recommend referring to its documentation or contacting its developers.
If you're having any trouble with the Dropbox API itself, we'll be happy to help, but we'd need some more information. In that case, please reply with:
