Based on my knowledge, Teams can be used for work/education (organizational accounts) or for personal use. The error “looks like you’re not using Teams yet…” usually appears when Teams doesn’t detect that your account is provisioned for an organization, so it might be a sign‐in flow mix‑up if the service is expecting a different account type.
- Confirm you’re using the correct Teams app experience:
• Microsoft Teams mobile app can support both organizational and personal accounts but sometimes may default to trying to sign you in as an organizational account. When you tap “Sign in,” double‑check if there’s an option (or a prompt) to sign in with a “Microsoft account” (for personal use) versus “Work or school account.”
• If you have multiple accounts logged into your mobile device (or in the Teams app), the app might be pulling the wrong one. Try signing out of all accounts in the mobile app and then adding your Gmail‑based Microsoft account as a personal account explicitly.
- Clear Teams app data completely:
• Although you mentioned reinstalling the app, on Android some residual data may persist unless you manually ‘Clear data’ from the phone’s Settings > Apps > Teams > Storage.
• After clearing the data, restart your phone and then try signing in again.
