Autocomplete results stop showing

I'm using the Autocomplete UI component using launchActivityForResult() with the following code:

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        if (item.getItemId() == R.id.search_button) {

            // Start the autocomplete intent.
            Intent intent = new PlaceAutocomplete.IntentBuilder()
                    .accessToken(Mapbox.getAccessToken())
                    .placeOptions(PlaceOptions.builder()
                            .language(Locale.getDefault().getLanguage())
                            .backgroundColor(Color.parseColor("#EEEEEE"))
                            .build(PlaceOptions.MODE_CARDS))
                    .build(getActivity());
            startActivityForResult(intent, 1);
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == 1) {
            if (resultCode == RESULT_OK) {
                CarmenFeature feature = PlaceAutocomplete.getPlace(data);
                initializeWeatherData(feature.center().latitude(), feature.center().longitude());
            }
        }
    }

When the app is first installed, everything is fine, and it seems to work the first several times, but after a while (or maybe a certain number of searches?) it stops returning any results, either while typing or after clicking the search button. Is this an issue with the API or something I've written? I assume it's in my code, but I don't know how to debug it and view the calls and responses. Gif of behavior is attached below, running on Google Pixel 3XL, Android Q (API 29).

I have tested on multiple Wi-Fi networks, as well as mobile data, with no luck. Once it stops working, it doesn't come back until I uninstall and reinstall the app.

Start by reproducing the failure through the PlaceAutocomplete.IntentBuilder flow, including repeated searches until results stop appearing. Inspect the API calls and responses during a working search and after failure, then determine what change prevents results from disappearing until reinstall. Done means autocomplete continues returning results across repeated searches and the behavior is verified on the reported Android setup.
