Apple Arcade Oceanhorn 2 Problems

I have gotten all the way to the end where I am supposed to fight the oceanhorn, but it isn't there...I can only hear it say "Trim" every few moments. Trin and I are thrown off the hover bike and the Oceanhorn shows up, Trin throws her boomerang at him and then he isn't there any more. I can walk around looking at stuff, and every now and then Trin says, "Here this might come in handy," and I am tossed a coin, but there is no Oceanhorn. But I can hear him saying "Trin" every few moments. I've gone through the mirror back in time twice, but it hasn't helped. I would like to finish this game, but it appears to be broken. Any suggestions/help would be appreciated. Thanks
