Hey there ​@matt_reilly_fundrise! Emily here from Support Engineering at Intercom 👋🏼Thanks for flagging this -we’re tracking a known issue in the latest Intercom iOS SDK that can crash inside ListBlockView.configure when rendering certain message content on iOS 26.0.1. The failures typically occur when messages include bulleted/numbered list blocks during conversation cell layout.This has already been reported to our team and awaiting a fix from the product team.Immediate workaroundsTemporarily rewrite messages that use list formatting (bullets/numbers) to plain paragraphs to avoid the list rendering path.If a specific automation/workflow triggers this, disable it or adjust the content until a fix is confirmed.As a fallback, roll back to a previously stable SDK version you’ve verified in your app.Our engineering team is actively investigating and correlating these reports.
