Is anybody else having issues with Multitrack DAW and iOS 18.3?
I opened the app after updating to iOS 18.3.1 and all my files have disappeared, but when I looked at the App data in Settings, the App size is still the same, suggesting the data is still there but it’s no longer displayed.

When will the app be updated so it keeps pace with IOS?

Hmm, no, there shouldn’t be any problem with iOS 18. The settings (general > iPhone storage > MultiTrack) won’t display folders (songs) so to make sure, you could use Finder (Mac) or iTunes (windows) file sharing to check for sure.

First make sure this isn’t something like multitrack displaying the inside of an empty folder. Use the back button (upper left) in the song menu of multitrack, to get back to the root Documents folder.

If that’s not it, connect your device to a computer and browse the device and tap the File Sharing tab, to see what’s really in the documents folder. You can also use iTunes on a pc for this.

There is a big update coming but nothing has changed in the file management code, so let us know how you get on. Hope this helps
