@msrutek-paylocity Can you tell us how many of these occur? Can you share the Apple log?
Also we've released 3.3.1 please upgrade and let us know if it solved the issues

MikePendo commented 1 month ago

@msrutek-paylocity I am not sure about that crash (it seems like apple crashes on loading some Bundle). Any chance you might know on which page it happens. And please if possible provide full Apple @orendayan Lets open a TSI issue and see if we manage to reproduce same stack trace on our side

msrutek-paylocity commented 1 month ago

@orendayan @MikePendo

Currently, there are just a few crashes. We do not yet know the exact page or steps to reproduce.

Unfortunately, also here none of the crashes can be found in the Apple crash logs, as the users don't have sharing feedback with developers turned on.

@msrutek-paylocity We have opened a TSI with apple to have more insight on the issue. We are waiting for apple response for any reason of the crash and how to avoid it.

msrutek-paylocity commented 1 week ago

@TehilaTaub @MikePendo @orendayan We've got a couple of more occurrences.

In some of them, there's

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000

which might indicate trying to access a nil property. Is there a way of making the underlying code safer?

TehilaTaub commented 1 week ago

@msrutek-paylocity Thank you for following up. Any chance you have the full crash log in the case you attached? We are still in communication with Apple on this one.

msrutek-paylocity commented 1 week ago

@TehilaTaub unfortunately, we cannot see this particular one listed in Apple crashes.
