We first noticed this issue on August 26th and it is growing. We use the key
“com.atlassian.servicedesk:simplified-general-service-desk”
to create a project for our app. This is now failing for some customers. We do now see other project keys that did not exist.
The change is certainly not documented. According to the Jira platform docs, com.atlassian.servicedesk:simplified-general-service-desk is a correct key and the other 2 are not. Please open an incident with developer support.
My guess is the team rolling this out neglected the developer impact. Hence, it’s an incident. I hope you’ll feel like you can make the incident public so other Marketplace vendors will know what’s going on.
