Hello @mehulios, thank you for reporting this issue. We are looking at this in our current work for the next major release. And if this issue doesn't show up in that next release, we will investigate what we need to backport afterward.

@louis-launchdarkly Do we have any update on this issue?

Hello @mehulios, I am really sorry for missing the reply to this. I wonder does the 6.x SDK released on May 4, 2022, fixed your issue? Currently, the iOS SDK 9.0.0 was released last week and had quite a bit of rearchitecting in place. Please let us know via https://support.launchdarkly.com/hc/en-us if you still encounter the issue - LaunchDarkly support team has dedicated engineers for customer issues and will not miss a reply like this. Once again, I am really sorry for this late reply.
