Take a protected backup and review release notes before installing an approved upgrade. Do not downgrade an operational workspace without a documented compatibility procedure.
For connection issues, verify the Server is awake, endpoint/TLS trust is correct, and firewall access is configured. Application connection settings remain available before sign-in.
Use the matching OS package manager or app uninstall process. Application removal can retain user data; it is not a verified data-erasure procedure. Follow /docs/INSTALL.md and /docs/CONFIGURATION.md for exact instructions.
