@Xiaoye220 thanks for the report - version 4.13.0 is from back in April 2018 and we've had a major version update since then with many changes to InstanceID.

Is it possible for you to update to the latest version and see if that resolves the issue for you? The cachedKeyRefWithTag: call in InstanceID doesn't exist anymore.

InstanceID is also now open source which should help with tracking things down if it does happen again.

There's not much we can do for old versions other than suggest updating to the latest, since this should be fixed now. Please do so if you can and re-open the issue if you run into it again!

[Xiaoye220]

Thanks a lot :)
