Not all recordings in directory are displayed in player

[xxyxxyxyx1]

I got a new phone and manually moved my old recordings into the recordings directory on the new phone. I was surprised to find that the old recordings are not displayed in the player list, only ones made with the new phone. Now, in order to play recordings made on the old phone and the new phone, I need to use a different app.

Switching to a new phone is something every user will do eventually, and there should not be such a major loss of functionality upon switching.

Is it possible to edit or rebuild some app cache to include all recordings currently in the recordings directory?
