@Ghamza-Jd Which SDK version do use? is it a native? steps to reproduce? Any chance you can make the bug according to bug format?
Hey @MikePendo, thanks for the response. I have updated the description.
@Ghamza-Jd If you updated to the latest SDK will u still have a crash, 2.19 is an old version we have fixed a lot of things since then
Will update and get back if the issue is resolved. Thanks!
I've updated it to version 2.22.1, and we found another issue with initializing the queue. And we couldn't reproduce the first issue

@Ghamza-Jd Very strange we didnt get any complains from other customers yet. So now you see 2 different crashes. Let's have it more organized. Could you please open 2 different issues with those 2 different crashes. (any chance you could add a full apple crash log, it might have some additional Info that can help us) Regarding the last crash I don't think it's related to Pendo (I might be wrong). Yes, we see Pendo in the stack trace as we use swizzling BUT the call is propagated further to apple methods without any issue, and the issue happens in the end. If you remove Pendo will u be able to reproduce the last crash?
Sure, I will open two other issues, remove Pendo, and check if the app crashes. First Issue Thanks!
Platform + Version iOS 16
SDK Version 2.19.1.6575
Framework Native
Describe the bug
We've been facing crashes on our iOS app from the Pendo library with SIGABRT.
The issue is freeing an unallocated memory.
Then the system calls abort.
Logs
Additional context
We're tracking screen views (we're not depending on the out-of-the-box service), and we're tracking some of the features being displayed (we're hiding some features behind a feature flag, so we want to have insights about what is being displayed). When switching between screens, the crash happens. It is inconsistent, but we suspect sending multiple track events simultaneously caused the crash.
