A simple troubleshooting framework
- Define exactly what changed and when.
- Check whether the issue affects one user, one device, or everyone.
- Separate local device problems from network or cloud-service problems.
- Record error messages before changing settings.
- Use official documentation when a step affects accounts, billing, licenses, or security.
This framework is educational and does not replace professional diagnosis for critical systems.
