Convo List does not handling a long list very well

[jmozzart]

I have more than a hundred conversations and this app is not user-friendly with such a long list.
Below is the list of the issues I noticed:

• It will take to finish loading the last in the list to show the conversations list. So if you have a 500 in the record, it will take several seconds for the list to show up.
• After loading the list, the messages in the conversation will load, and it will take another seconds for us to use the app properly.
• If you click a conversation while loading, it will return an error "Cannot read properties of undefined (reading 'length')"

Message List can handle a long list of messages in a conversation very well. I hope Infinite Scroll can be implemented in Conversations List. In most cases, we will only need the most recent messages not more than 50.
