Impact: Chat unavailable when using JavaScript SDK along with ad blockers that have privacy tracking enabled
When: Starting Friday, May 28th around 11:30p EDT
Cause: We’ve recently been made aware of a change made to EasyList, a filter list provider for extensions such as Adblock Plus and uBlock Origin, where our WebSocket domain has been blacklisted. As a result, end users utilizing Adblock Plus, uBlock Origin or any similar service that uses EasyList as a source will be unable to connect to Sendbird.
This issue impacts JavaScript SDK implementations only when used with ad blockers that have privacy tracking enabled.
Next Step: We are actively engaged with EasyList to address this and hope to resolve it as soon as possible. In the meantime, end users can utilize some potential workarounds below: - Whitelist the sendbird.com domain (configuration varies from ad blocker to ad blocker; suggested pattern: @@||*.sendbird.com/*) - Turn off the blocker for the page/site where chat is utilized.
Sendbird does not utilize any user information for retargeting or any advertisement.
