On April 23, 2019, an update was rolled out to our iOS app, which contained a bug that caused some recent channel message history to disappear. We've fixed the bug and submitted an updated app version to the App Store. The updated app version will start rolling out today.

We've honed in on the issues with iOS message history and submitted a fix which will be made available through an update to the App Store in the next few days. If you're still seeing any trouble with viewing channel history after the update, please write into firstname.lastname@example.org.

Customers using the iOS app may be unable to view the full message history of recently created channels. We're on the case, and we apologize for the disruption as we look in to this.
