Hi StephenQueries,
Thanks for posting. It looks like you want to know about exporting from Music Memos to Voice Memos, and we're happy to assist.
You mentioned you're using iOS 14.2.1. If you haven't seen that prompt coming up at all, it may be helpful to Update your iPhone, iPad, or iPod touch to iOS 14.3 and then check for the prompt.
Also, if you saw the prompt before and tapped OK, that will dismiss the prompt for seven days as shown here: Transition from Music Memos to Voice Memos
In Music Memos version 1.0.7, you can export your Music Memos recordings to your Voice Memos library. Here's what you need:
Open Music Memos. When “Recording is moving to Voice Memos” appears, tap Export. It can take several minutes to export your recordings to Voice Memos depending on the size of your library.
If you don't want to export at this time, tap “OK” to dismiss the “Recording is moving to Voice Memos” window for seven days.
Once you've exported all your Music Memos recordings to Voice Memos, your recordings appear in Voice Memos in a folder titled “Music Memos.” If you encountered an error while exporting, you might need to free up space on your device or wait until your Music Memos recordings have finished updating from iCloud.
If you create new recordings with Music Memos, you'll need to copy them to Voice Memos to make sure you keep them."
We hope this helps. Take care.
