Can you please help in explain what is meant by "client side context change "
What i have tried from my end

1. Added few tags in the new conversation  - Able to see the tags in the zendesk portal
2. Tried updating the tags - by adding new tags in the ongoing conversation - Not able to see the new tags in the zendesk portal.
3. Tried clearing the tags and than passing the updated tags  - Still the old tags are seen in the zendesk portal.

[Zendesk.instance.messaging setConversationTags:@[@"promo_code", @"discount"]];

[Zendesk.instance.messaging clearConversationTags];
