I've been trying to play with the ElevenLabs app and I can't figure out how to have it read files from my Dropbox. I go to "More," when I want to import, and all I see is what's on my phone. I feel like I'm not nearly smart enough to use this app. Is there an audio tutorial or something I can listen to? I do know someone said that .pdf's work better than text files, but other than that I'm absolutely at a loss. I'd love to get it figured out though.
