When you sign-up to Cloud from WAC, the provisioned instance would be configured as the following:

• UI language: Atlassian account language
  • most of the times this is the same as the display language used in WAC
• indexing language: English
• Default language: English

For non-English customers, the product looks ready to use in their locale at the first glance, so they start creating their first project. However, since the background language settings are English, this results in English projects getting created (issue types, SLA name, report name etc follows the default language setting at the time of project creation).

To prevent this and provide an international-friendly experience, would be great if the defalut Jira setting inherits the language used in WAC sign-up.
