Famille de feuilles de calcul Microsoft avec des outils pour l’analyse, le graphique et la communication des données.
Hello, I’m Virginia a fellow Windows user.
Do you have a Microsoft 365 subscription? If not then the apps will be in read only mode.
Older phones/devices were allowed to use these apps if the screen was small however in recent years Microsoft changed this (I know this affects Apple devices) so that large screen devices require a subscription. I believe the cut off point is about 9/10 inches.
The only other option is to use the free versions via your MS account.
However this doesn’t explain why you can edit & save via a different route so perhaps it’s a feature. Have you signed in to those apps?
