Filesystem with Quasar on android 11/Xiaomi

Hi,
I have basically same app written with Ionic and Quasar. I am using Filesystem 1.0.6.
I have all my manifest settings done.

and…
Ionic App works fine on Xiaomi, saving the file to the storage
Quasar app works fine on emulator and my Samsung S10e (Android 11)
Quasar app doesn’t work on Xiaomi Lite 11 phone.

I have tried to recheck everything and can’t find an issue. Any help would be great:

async loadDataFile() {
      alert("Loading of data...");
      const permissions = await Filesystem.checkPermissions();
      alert(permissions.publicStorage);
      const fileContent = await Filesystem.readFile({
        path: "push-up-tracker_Data.json",
        directory: Directory.Documents,
        encoding: Encoding.UTF8,
      });
      alert(fileContent);
      const data = JSON.parse(fileContent.data);
      alert(data);
      console.log(data);
      this.$store.dispatch("overwriteStore", data);
    },

The third alert(fileContent) does not pop-up.

All the best to everyone
