angularjs ng-if scope JavaScript

This might be a silly question, but Hey everyone, I'm running into an issue that's driving me crazy. I'm facing a frustrating issue with `ng-if` in AngularJS 1.8 where it doesn't seem to update the DOM as expected when the conditions change. I have a setup where I'm using a service to toggle a boolean property based on user interactions, but the corresponding elements aren't being shown or hidden correctly. Here’s a simplified version of my code: ```javascript app.controller('MyController', function($scope, myService) { $scope.isVisible = myService.getVisibility(); $scope.toggleVisibility = function() { $scope.isVisible = !$scope.isVisible; myService.setVisibility($scope.isVisible); }; }); app.service('myService', function() { var visibility = false; return { getVisibility: function() { return visibility; }, setVisibility: function(value) { visibility = value; } }; }); ``` In my HTML, I have the following: ```html <div ng-controller='MyController'> <button ng-click='toggleVisibility()'>Toggle</button> <div ng-if='isVisible'>This is conditionally rendered!</div> </div> ``` Despite toggling the button and changing the `isVisible` property, the `div` with `ng-if` does not show or hide as expected. I've confirmed that the value of `isVisible` is toggling correctly by logging it in the console. I also tried using `$scope.$apply()` after changing the visibility in the service, but that didn't help either. Is there something I’m missing about how `ng-if` works with dynamic properties or is there a specific scenario in 1.8 that could cause this issue? Any help would be greatly appreciated! This is part of a larger CLI tool I'm building. What's the best practice here? For reference, this is a production application. Hoping someone can shed some light on this.
