Hello, I’m having a similar problem uploading audio files recorded on IOS. They are formatted as .m4a and I recieve the following error message:
Error. This file was rejected because its MIME type is invalid. Its MIME type is: audio/x-m4a
I followed your instructions for the *.msg files above, but still am seeing the same error on *.m4a uploads.
I’m happy to start another thread, but I figured I’d post here as it’s a similar issue. I have the pro version, btw.
Thanks!
