Hi @Zara !

Issues like this are best taken up with the Intercom Support team. I’ll go ahead and send this question over to them. They will reach back out to you via the email address that you signed up with. The first step that you will want to take sure is to make sure you have the most recent version of the Intercom iOS SDK installed since having an outdated one installed is often the cause of many mobile issues. You can find that SDK repo here.

We have this issue and it is iOS17 only. 

We plan to upgrade to the latest intercom-react-native version, from intercom-react-native 3.0.5
