To remove a progress instance from your account, follow the instructions:
Head to the Main Menu, then to Progress.
In the Progress section, select the progress you would like to remove, and click the trash can icon.
You will have to confirm your decision to remove the progress instance by clicking the Remove button.
After you have confirmed the removal, a waiting period begins (the duration of which depends on your Capitol level and other parameters).
When the progress is ready for removal, you will see a trash can icon with a check mark on it. Click on the progress to confirm the removal or to restore the progress.
After you press Remove, the progress will be removed from your account.
Can I remove a seasonal progress?
Yes, you can do so as soon as the seasonal progress becomes post-seasonal, i.e., when the current Seasonal Kingdom ends.
When the Seasonal Kingdom is active, it is not possible to remove progress instances created in the current event.
Can I retrieve a progress that has already been removed from my account?
No, if a progress has already been removed, it cannot be retrieved.
