checksum does not match error troubleshooting steps

• [x] First, check if the problem was with your download. Delete the downloaded file (its location will be pointed out right under the Actual shasum line) and try again.
• [x] If the problem persists, the cask must be outdated. It’ll likely need a new version, but it’s possible the version has remained the same (happens occasionally when the vendor updates the app in place).

Latest version on vendor's website

3.0.0

brew cask _stanza version touch-bar-simulator

3.0.0

[Penguinlay]

Automatic update when the app is launched is fine. But, even after update, the version remains 2.0.0 in terminal. Perhaps this should mark as auto update by default?
