This problem analyzer will exclude any IsotopeSubscription references in deployments.
What Triggers this Problem Analyzer?
If your deployment package contains a reference to IsotopeSubscription then the problem analyzer will be triggered.
What problem is it solving?
Salesforce introduced a new standard button as part of a non-standard subscription. It ended up in people's orgs as an exclusion. If you try to move that exclusion to another org, you get a failed deployment because it's not a valid button name.
This problem analyzer will remove the exclusion and therefore make the deployment more likely to succeed.
How does it work?
Gearset will identify the IsotopeSubscription metadata type and remove it from the deployment package.
