When creating a custom theme, it takes ~15-25 minutes to fully create the theme. If the user navigates to the "custom themes" listing, chooses the theme that is being created and clicks on any of the files, the theme creation will immediately stop and cannot be started again. This often results in broken theme creations because users do not give it enough time to finish creating.
Ideally, users should not be able to access a new theme at all until it is finished being created.
Update 8/9 - this has been completed! You can no longer access a theme until it is created.
We should not let you choose that theme until it is done being created. We don't have a timeline for this fix yet but follow along for updates!
