Hey @azanton,

Thanks for using the dev forum! It is good to see you again :slight_smile:

I know this may not be reproducible but is there any additional information? Did it happen right when the user backgrounded the app, has hit happened multiple times, was there any specific action in the meeting before backgrounding that could be related?

Thanks!
Michael

Hi @Michael_Condon,

Thanks for the help again! :smiley:

So far it has only been encountered once, and the crash happened right after going to the background.

Hey @azanton,

You are very welcome :slight_smile:

Unfortunately without reproduction steps or crash logs, there is not a whole lot we can do. Please monitor this and let us know if this happens again.

One cause for a backgrounding crash that I have seen before is the MobileRTCMeetingServiceDelegate becoming nil before it is used again by the SDK. It may be worth checking to see if that has happened in your application.

Thanks!
Michael

Hey @azanton,

The engineers have asked that you update to a later version as .0616 is no longer supported for bug investigations.

Thanks!
