To reduce resource usage and improve reliability, Clan Battle loading has been disabled for Clans determined not to be actively using any of the features related to Clan Battle loading.
To be clear, this is in reference to the battle lists shown on Clan Home > Battles, not the data shown on Clan Home > Clan Wars.
If your clan was incorrectly identified as not actively using Clan Battle loading, my apologies for the inconvenience. To correct this, your clan's Commander or any clan Admin on the site can turn Clan Battle Loading back on by going to Clan Home > Edit, checking "Enable Loading Battles", and then clicking Save. You can also Contact me and I can enable it again.
