I'm sure this has been discussed but I couldn't readily find it.
I frequently the "no such file" error message when attempting to import a song from Google Drive and to date, I've gotten the message every time I've attempted to import files into a multitrack.
Additionally, I get the error message nearly every time I attempt to import a pdf, but I have a weird work-around for that. If I get the error message when attempting to import the pdf I go to "edit lyrics" and import it there but cancel it rather than save it. Then I go back to "PDF Document" and the pdf downloads exactly as it should. Weird, huh?
I'm running on iPadOS version 16.3.1
