There is a new iOS app that was released a few days ago that works on my iPhone. The reviews show some people still have issues with iPads, but I am sure they will be worked out in a future update. Similar to metaverse, but refined and updated a bit as well. Only used it a few 30 minutes today so far, but stable for me and I just wanted a chat feature and it even looks like a chat on a mobile device with the bubble chat.
