It's the same pattern I see all the time: 
Lots of first level replies + Conversations that branch out from some of these replies (but rarely branch out widely)

Have you tried displaying it like chat messages (starting from the second level of replies)?

 oh, it seems good, I will try this now. I still experiment the new event screen. 

 hmm, I see chat layout isn't good if reply have long content, include few images or videos. Do you have any ideas for it? 🤔  

 Do you happen to have a screenshot? 
I don't see what makes the difference with a thread lay out in this case 🤔  

 I will send you some screenshots later. 

 Also, I don't have those issues with my chat bubbles (so far). I can send you some designs later if needed.
