Glow not recognizing ovulation?

I came off BC in jan and started using this app about a week later.  My first cycle off bc was 65 days, so glow assumed my next cycle would also be 65 days.  However, I got a positive opk followed by temperature rise earlier this week.  Glow had predicted my fertile week to start mid next week, but shouldn't it have corrected once it got the data about the opk and temps (and CM)?  I would like the positive reminders about waiting before testing and other hints.  Is there something I have done wrong?
