Audio recording not showing in Music app

Device : Fairphone 2 Build : e-0.7-n-2020011737872-dev-FP2

--- What happens ---

When you record an audio file with the recorder app (Magnétophone), it does show in the Music app (Musique), nor in the audio files (Fichiers > Fichiers audio).

Yet it can be found when exploring the files starting from the device itself : Files > FP2 (= the device) > Music > SoundRecords.

After a reboot, the file appears normally into the Music and audio files.

--- What should happen ---

Recorded wav file should appear immediately into the Music app and be part of the "audio files".

--- Steps to reproduce ---

Open recorder app

Record audio

Open Music app : no new file with the name starting with SoundRecord

Open Files app, then Audio files : no new file with the name starting with SoundRecord

Open Files app, then , browse to Music > SoundRecords : see the new file

Reboot device

Open Music app : the new file is there

Open Files app, then Audio files : the new file is there

--- Comments ---

Issue may not be related to the recorder app but to the indexing of the music/audio library.
