• iOS

I haven't checked on Android

Current Behavior

When Haptics.vibrate is called too often, especially while the previous calls haven't been finished yet, the phone will hang.

Expected Behavior

The haptics are triggered from a different thread than the main one so we don't block the app completely when doing trivial actions.

Other Technical Details

As stated per the documentation, https://developer.apple.com/documentation/corehaptics/preparing_your_app_to_play_haptics/#3200019, core haptics is thread safe so it can be called from wherever without impact.
