Hi @Abdallah_Mohammed

When getting GrouChannel instance, it is failed.

  1. What is your SDK version?
  2. How did you start ChannelSettingsFragment?
3

SDK version is 30
We start ChannelSettingsFragment using Builder, you can see attached code snip

class CustomChannelSettingsActivity : ChannelSettingsActivity() {

    override fun createChannelSettingsFragment(channelUrl: String): ChannelSettingsFragment? {
        return ChannelSettingsFragment.Builder(channelUrl, R.style.SendBird_Custom)
            .setCustomChannelSettingsFragment<ChannelSettingsFragment>(CustomChannelSettingsFragment())
            .setUseHeader(true)
            .setHeaderTitle(getString(R.string.sb_text_header_channel_settings))
            .setUseHeaderLeftButton(true)
            .setUseHeaderRightButton(true)
            .setHeaderLeftButtonIcon(
                R.drawable.icon_arrow_left,
                AppCompatResources.getColorStateList(this, R.color.black)
            )
            .setHeaderLeftButtonListener(null)
            .setOnSettingMenuClickListener(null)
            .build()
    }
}

Could you update our UIKit SDK to 2.2.0? (It supports local caching)
Plus, Please check channelUrl is valid.
