I somehow went over 40 minutes on a free account?

EDIT: For my meetings today, they were capped to 40 minutes. Looks like it's just the first one you host!

I had a birthday Zoom with my family on Thursday, which I hosted, and despite having a free account and never giving Zoom any payment info, we went over 40 minutes. As it was approaching 40 mins, I said that we might need to leave in a few minutes, but my dad told me he got a message saying I extended it to unlimited, but I didn't do anything.

Looking at previous posts on the subreddit, there's a bit of conflicting information, but apparently you get unlimited for the first time/times hosting.

1. Is it the first time, or first few times, and if it's the first few, is there any way of predicting when it will start caring about the limit?
2. Does it count by total number of meetings I hosted, or just the number of meetings I hosted that went over 40 minutes?

I have another meeting in about 9 hours, and want to know if it'll be limited to 40 minutes or not. It's fine either way, just helpful to know if I have a hard end time.
