@msrutek-paylocity Any chance your app is on appstore and we could try to run it on our end

[msrutek-paylocity]

@MikePendo Hello, yes, the app is available on the AppStore - https://apps.apple.com/en/app/paylocity/id652438572 - however, an account is required. Could you share an email that we could send test credentials with?

[MikePendo]

@msrutek-paylocity Any way you can provide us some sample user to try ?

[MikePendo]

@msrutek-paylocity ios-sdk@pendo.io is our email

[0xkuj]

@msrutek-paylocity will that be possible to provide us some sample user so we can reproduce this? other crashes should be fixed in the future

[msrutek-paylocity]

Hi @0xkuj @MikePendo , just sent an email with credentials you can use to log in into the app.

[0xkuj]

we improved our scanning mechanism to scan the minimum number of objects possible, and we believe it may resolve your crashing issues. in addition to that is will be highly recommended to change the integration with an addition flag as below:

let options = PendoOptions() options.configs = ["enableTextCollectionSwiftUI":false] PendoManager.shared().setup(prodAppKey,with: options)

this flag is meant to reduce the texts collection via reflection and base text collection on accessibility elements only.

this was done in our latest 3.2.1 HF fix, please try upgrading and let us know with your results.

[msrutek-paylocity]

@MikePendo @0xkuj Thanks, we've updated the library and used the suggested options configuration.

However, it might take a couple of weeks until this gets to the production users.

We'll let you know if this issue still occurs.

@msrutek-paylocity, thanks for the update. I'm closing the issue for now, please reopen if needed.
