Checklist

• [x] I am using the latest version - v1.4.5 (F-Droid Build)
• [x] I checked, but didn't find any duplicates (open OR closed) of this issue in the repo.
• [x] This issue contains only one bug. I will open one issue for every bug report I want to file.

Steps to reproduce the bug

1. Make or receive a call via Koler.
2. Merge another call to make it a conference call
3. Tap on Manage Conference button.

Actual behavior

When you tap on manage conference button to see who all are there in a conference call, it does nothing, and app stops responding after a while. You cannot even disconnect the call. I had to ask the other person to do it.

Expected behavior

Upon tapping Manage Conference button, a list of numbers/contacts in the conference shows up, with a disconnect button next to each row.

Device info

• Android version: 11
• Device model: Motorola moto G40 Fusion

I've experienced this bug too, though the conference did actually merge, and I was able to hear all participants.

I was able to hear all participants.

Of course, I'm talking about managing a conference. One should be able to disconnect people in conference if they're the host. The app just freezes leaving you on a conference call. No mute, no disconnect works.
