General troubleshooting steps

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command. -> my system ready to brew
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match error.

Description of issue

There is a checksum error however checking the version with ‘brew cask _stanza version’

10.4.0.1771,531

is the same as last available version at

https://install.appcenter.ms/orgs/rdmacios-k2vy/apps/microsoft-remote-desktop-for-mac/distribution_groups/all-users-of-microsoft-remote-desktop-for-mac

so I’m affraid I don’t really know what is wrong and what I can do.

Command that failed

brew cask upgrade microsoft-remote-desktop-beta

or

brew cask install --force microsoft-remote-desktop-beta

or

brew cask uninstall microsoft-remote-desktop-beta
brew cask install microsoft-remote-desktop-beta

Output of command with --force --verbose --debug
