Ionic pop in 3rd level view does not update 2 level page (stroage data change)

Ionic Framework ionic-v3
1

Hi all
I got 3 level deep nav views.

In the first view I get data from local storage and output a list

page 1

  getPrograms() {
    this.storage.get("fetchedData").then(val => {
      if (val.hasOwnProperty("programs")) {
        this.programs = val.programs;

        for (var i = 0; i < this.programs.length; i++) {
          if (this.programs[i].exercises.length) {
            this.exercises.push(this.programs[i].exercises);
          }
        }
      }
    });
  }

 itemTapped(event, program) {
    this.navCtrl.push(Exercises, {
      programs: program
    });
  }

and then in the second view I get data with params from the first view and generate another list (from params data)
page 2

  this.currentProgram = this.navParams.get("programs"); .....etc
.
.
 getExercises() {
    if (this.currentProgram.hasOwnProperty("exercises")) {
      this.exercises = this.currentProgram.exercises;    
    }

seeDetails(event, exercise) {
    this.navCtrl.push(ExerciseDetails, {
      exercises: exercise
    });
  } 
  }

In the third view I get data from the second view with params
page 3

this.item = navParams.get("exercises");

and then when user submit some changes and they are posted to external API I do the change to the storage value

getUpdatedData() {
      this.storage.remove("fetchedData").then(() => {
//get refreshed data from endpoint
        this.programsService.getPrograms(userhash).subscribe(res => {
          if (res != null && res != undefined) {
                this.storage.set("fetchedData", res).then(() => {
                this.loader.dismiss();
                this.navCtrl.pop();
              });
          }
        });
      });
  }

So when I pop from the 3 level view e there’s no update in the 2nd level data (storage is changed so this should be somehow reflected in the first view and then passed to second view)
