   We're aware of an issue affecting Lightning Web Runtime sites that use rich text or HTML content. A subset of customers may see missing styling and broken layouts, on their site pages. The issue appears related to a recent update to a service. We're exploring multiple paths to resolution. We'll provide an update in 30 minutes or sooner if additional information becomes available

   We've identified the cause as a recent update to a site component that changes how rich text and HTML content displays. We’ve reproduced the issue and confirmed it can affect any Lightning Web Runtime site on the current release. We are preparing and validating a configuration change that will revert the recent update. We will deploy this fix as soon as we are able to verify that it restores services to users. We'll provide an update in 30 minutes or sooner if additional information becomes available, and apologize for any inconvenience this issue may be causing.

   We continue to test and validate the configuration change to ensure this restores services to users. We’re also evaluating whether a configuration change can correct the display while also keeping the current update. We'll provide an update in 30 minutes or sooner if additional information becomes available, and apologize for any inconvenience this issue may be causing.

   We’re building a fix for the formatting issue rather than reverting the earlier change, following further investigation and testing. We’re bringing in additional support to develop this fix. We don’t yet have a timeframe for developing and testing this. Additonaly, customers should not republish their sites while work is ongoing. We’re developing a Knowledge Article to help customers in the short term. We will provide the next update as soon as a can clarify a timeframe for the development of the fix forward, or if additional information becomes available. We apologize for any inconvenience this issue may be causing.
