android.view.WindowLeaked: Activity com.sumup.merchant.reader.ui.activities.CardReaderPaymentAPIDrivenPageActivity has leaked window DecorView@974c875[CardReaderPaymentAPIDrivenPageActivity]

I had to upgrade from 3.2.0 to 3.3.0 and getting this runtime error since then. We use this sdk in a cordova plugin like this:

      SumUpPayment payment = SumUpPayment.builder()
        .total(amount)
        .currency(currency)
        .title(title)
        .skipSuccessScreen()
        .build();

      Runnable runnable = () -> {
        SumUpAPI.checkout(cordova.getActivity(), payment, REQUEST_CODE_PAYMENT);
      };

      callback = callbackContext;
      cordova.setActivityResultCallback(this);
      cordova.getActivity().runOnUiThread(runnable);

This was working fine with 3.2.0, but since 3.3.0 I get the error in the title, with the following stack:

Before this call we check if the user is already logged in with this:

 Runnable runnable = () -> {
        callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK, SumUpAPI.isLoggedIn()));
      };
      cordova.getActivity().runOnUiThread(runnable);

Which works fine

Any suggestions? I couldn't find much info in the release notes of 3.3.0:/
Thanks in advance.
