Hi,

I use Sendbird android sdk version 3.0.67 and got ConcurrentModificationException on updateJoinedMemberCount.

Here is log from my Crashlytics:

  Fatal Exception: java.util.ConcurrentModificationException

Any suggestion how to fix the problem?
Thanks

Hi @razibkani
This issue seems to be fixed in sdk 3.0.69 version.
Currently, the latest version of our sdk is 3.0.156. The version you are using was released two years ago, so it seems too old. We recommend updating to the latest version to use.
