If you recorded with no signal and synced later, your audio arrived intact but every voice became “Speaker 1”. That is fixed.
What changed
Speaker labels are written to the phone the moment you name them.
Sync merges labels after the audio, so nothing is overwritten.
Notes affected by the bug have been repaired automatically. You do not need to do anything.
Thanks to the 41 people who sent us examples from trains, planes and one submarine tour.
