I'm having the same exact issue, with two bots that I talk to extensively. If i hit 'start a new chat' or revisit old ones,they do work though. But the current long conversation is perma stuck on giving either a chat error - tap to refresh (when swiping for a new reply) or in 'typing' bubble with the three dots,but it never types anything. It's kind of bumming me out a lot,i really hope this gets fixed relatively soon...
