Amino harry potter?

Hello guys!
I installed the version of the amino harry potter app for the Brazilian community, but I believe it is the same English app in general with some modifications.
My question is this:
 even if you do not use the Portuguese version of the app, could anyone use the chat? VoiceOver loses focus in the middle of the messages and I was not able to go to the last message.

#1 I don’t know

I don’t know about this app. Is that a game? Is this a website or is it an app? Is it a chat room? I would need some more explanation if I should be able to help. I have never heard of Amino Harry Potter. Sorry if I don¨'t get things right.
