I'm trying to copy data from my Android phone to an iPad. I've tried copying the file to my Google Drive and downloading it on the iPad. The file is greyed out in the file explorer when I press import in the app. The option to "share" to Walk Out DJ is not available in the Files app.
Resolved: had to add .txt to the filename on the iPad.
Interesting... what was the file extension before you added the .txt? I can probably fix that if I can duplicate it here. Thanks for reporting the issue!
