How to add an additionnal mobile under my avastone abonnement?

Bonjour,
J’ai un compte et un abonnement Avast One qui couvre mon ordi et mon téléphone mobile.Mais puisque l’abonnement peut couvrir cinq appareils, je voudrais ajouter mon deuxième smartphone (Android Galaxy S23), mais je n’y arrive pas. Comment faire ?
Merci de m’aider…

First I don’t work for Avast and I don’t use Avast One so I can’t speak from personal experience.

What have you tried that is failing ?
You should be able to download the App from the Google store as you did with the other mobile installation.

In your Avast Account you should be able to include that installation in your subscriptions.
