Hello there.

I use Your SDK 6.0.0 in my iOS app.

Here is the crash I found in FirebaseCrashlytics:

Thanks for reporting these! Do you happen to know the steps to reproduce this? Likewise, if you can share the relevant code/parameters that the app was running at the time of the crash, that may be helpful.

Also, the latest version of the SDK is v6.2.0, which contains a few bug fixes since v6.0.0, so please update to v6.2.0 and let us know if that seems to resolve any of these. Thanks!

Yes, I anticipated this question, but unfortunately, I don't know the exact steps either, and I can only guess. Also, I can't reproduce the crash. I suspect the app's module is waiting for changes to the DropBox’s folders using specific cursors.

Just in case I attached fragments of the code. The suspect module is: KPDBSyncContentChangesObserver.

Also, the latest version of the SDK is v6.2.0, which contains a few bug fixes since v6.0.0, so please update to v6.2.0 and let us know if that seems to resolve any of these. Yes, I'm going to do this.
