Opening here because didn't find any issue similiar.

When I send an audio of more than 2 minutes takes too long to load on the messages, tested in different internets and devices and always the slowness to load bigger audios, also the timer gets stuck at "00:00" until the audio is loaded giving the impression that the audio is crashed or something. Would be nice a loading icon for waiting the audio and optimizing this loading if possible
