Mobile/Desktop Safari recorded audio doesn't playback in Mobile Safari

[akeybl]

Confirmed working:

• Record: Desktop Safari / Playback: Desktop Safari
• Record: Mobile Safari / Playback: Desktop Safari

Broken:

• Record: Mobile Safari / Playback: Mobile Safari
• Record: Desktop Safari / Playback: Mobile Safari

Behavior: Recording "waveform" and play button is shown, but nothing happens when touched. Can't move the cursor when attempting to seek.

If you'd like to, I'm happy to sit down and do a live debug session. If you have access to a Mac, will probably also repro in the iPhone simulator.

Strangely, upon recording in Mobile Safari (before pressing send) the waveform doesn't appear, and the playback button is replaced with the "no playback" symbol

[or-else]

I see cryptic errors in the console, without traces.

[Error] Unhandled Promise Rejection: EncodingError: Decoding failed

There is no simple way to debug it. Given that Apple intentionally cripples iOS Safari (for example, no push notifications) I'm inclined to just let it slide unless more people request support for it or someone pays.
