My problem is that the recordings overlap instead of being saved separately and placed in numerical order.
I created a “system” to save and reorder the Sound Recorder recordings, thanks to the help of the Community, which some time ago helped me to create this “system” (link).
The “system” consists in saving each recording in numerical order and when one of these was renamed / deleted, the new recording was inserted in place of the deleted / renamed one instead of continuing with the numbering.
RecordingWolf.mp3 (renamed recording)
Instead of saving “Recording5.mp3”, this recording will become “Recording4.mp3”
After the Kodular update, this system no longer correctly saves the recordings.
