We don't currently have a
tank command for uninstalling an app.
It is pretty easy to do manually however. Just go into the relevant environment config file (eg.
config/env/shot_step.yml) and remove the app entry by hand. Each app has its own "section" in the
.yml file in the form of an indented structure. Alternatively, if you just want to temporarily disable the app, there is a disabled option you can set - check out the documentation for that here.
