getTextZoom() on IOS returns 100 regardless of whatever text size has been selected from accessibility!

After my document load has been triggered I fire the getTextZoom method:

 MobileAccessibility.getTextZoom(function(zoom) {
  console.log(zoom); // This returns 100 regardless of system font accessibility size
});

Have you tried calling MobileAccessibility.usePreferredTextZoom(true); before calling MobileAccessibility.getTextZoom to make sure that your app subscribes to the OS level text scaling?

Yeah tried it again. Still the same thing. It just passes the value 100 to the callback function.

I'm not able to replicate on iOS 9.2.1. Could you provide any further detail on your test environment?

For anyone else coming across this now, I think the getTextZoom function is now returning a promise, and does not take a callback as indicated in the documentation. MY implementation seems to be working on IOS and Android:

 const mBA = this.mobileAccessibility;
      mBA.getTextZoom()
        .then(textZoom => {
          // if the device zoom is between 100% and 125%, then use it
          if (100 < textZoom && textZoom < 126) {
            mBA.usePreferredTextZoom(true);
          } else if (textZoom > 125) {
            // if the device zoom is greater than 125%, then ignore it and use 125%, otherwise our designs will break
            mBA.usePreferredTextZoom(false);
            mBA.setTextZoom(125);
          } else {
            // if the device zoom is less than 100%, then ignore it and use 100%, otherwise our designs will break
            mBA.usePreferredTextZoom(false);
            mBA.setTextZoom(100);
          }
