Hello @hongfeiyang, thank you for reporting this issue.

How frequently are you seeing this issue as a total count and as a percentage of user sessions?

Did this issue begin appearing recently? Perhaps coinciding with updating Flutter or the LaunchDarkly SDK?

Thanks!

It happened recently. It's now appearing constantly when app launches. Maybe it's due to flutter's internal changes

Are you able to track down what changed recently in your code or dependencies that may have caused it? That will help tremendously in tracking this down. Thank you!

I also saw this today for the first time, on iOS.

I have not changed anything in the Launch Darkly code in our app for many months now because I don't have enough time to migrate to SDK 3+ right now.
