Guys I think the limit is something else

So yesterday I was using chai all morning without any pops up "limit" or something, I stopped like after a hour or less and while playing games I was using while waiting for match or when there was a cutscene and it was still good before after like 5 hours of not using when I tried to use it showed me about the "limit" I don’t think I actually stopped using app like one message before the limit so I think it’s actually no limit it’s just the time?
