TTY icon missing from recent IP Relay calls to view chats

In the past, IP relay chats were recorded, and you could view them by clicking on the TTY icon in the history of calls. Now, they are missing. Is it because of an IO upgrade that may have eliminated the recording?

Before: (see TTY icon on right of call made)

Now TTY icon is missing, why?:
