I use Ionic-angular and I use the following code in some parts of my application:
<ion-spinner name = "circles"> </ion-spinner>
I commanded
ionic capacitor run android
I ran my app on both my real phone and the Android emulator And I have some problems
The first problem:
My ion-spinners do not spin
The second problem:
I used two tabs at the bottom of the program that activate their style does not work
The third problem: Some of the ionic icons are also invisible.
I had the same problem. I created a new project and used its styles. Many problems were fixed. But there are still some problems. Did you use this method? You can also use different spinners: https://ionicframework.com/docs/api/spinner
