Electron app: Recording extension doesn't record on sim

[thsparks]

When using the electron app, if I add blocks to record from the recording extension, it only runs for a very brief amount of time and doesn't actually seem to record anything. I'm guessing it might be a permissions issue with the computer mic?

Not a regression. Tried with the older release and same issue. @riknoll fyi,

Looks like the record icon is not displaying either
