Changes to iOS voice channels

I've been in contact with support, as initially I thought it was a bug. But I've been informed that it's a new change that I need to get used to. 

The problem is that the change really does seem like a bug. When I go to join a voice channel in any server on my mobile or iPad, instead of just joining the call I get a screen with a big JOIN button. 

It then takes you to what looks like a video call interface where you can see the default icon screens of everyone in the voice call. To access loud speaker, mute someone, or do basically anything that you could do before with one click, you now need to navigate a bunch of screens to do these things. 

This is an unnecessary change and causing an accessibility issue. 

Why do users need to see the video call interface when joining a voice chat? 
What do users need to find a tiny icon at the top of the screen to navigate to what used to be basic functions available at the bottom of the screen when in a voice call?
Why has the decision been made that users must now have to deal with multiple interfaces instead of just the one interface we had weeks ago, that has been the interface for years?

Steps to join VC and use loud speaker before change: [one interface]
- tap voice channel (join call immediately)
- tap speaker icon/button at bottom of screen
- swipe out of voice chat interface to access text channels

Steps to join VC and use loud speaker since change: [4 interface changes]
- tap voice channel
- tap Join Voice (green button)
  (get taken to what looks like a video call interface)
- tap little people icon/button at top right of screen
  (I worked this out by tapping everything, it's not clear)
- Voice chat interface will slide up. Tap loud speaker icon/button.
- Tap top half of screen/swipe down to be taken back to video call interface
- Swipe down again to access text channels

Can anyone from discord please explain the thinking behind this? Who decided that what used to be a 3 step, 1 interface process needed to become 6 step, 4 interface process that isn't intuitive and is an accessibility issue? As a disabled user, having to navigate through multiple interfaces makes the user experience incredible difficult. I'm now avoiding using the app on my phone, which is causing issues, as I often need to be on my mobile in voice calls.
