How to Check Your Azure Management Tools Version
Both Azure Powershell SDK and Azure CLI 2.0 are frequently updated to stay current. Older versions have limited shelf life.

If keeping the installed version of these tools up to date is an annoyance, I would suggest checking out Azure Cloud Shell as a possible alternative.
