Problem
The save/export button in the playback view is not working. This is a critical issue as it prevents users from exporting recordings, which is a core feature of the app.
Expected Behavior
The save/export button should successfully export/save the current audio segment to the device's Downloads folder or user-selected location.
Impact
CRITICAL - This prevents users from using the app for its primary purpose (exporting recordings).
Reported By
