Bell Schedule (For School)

I’ve been using this app for a while until it just stopped working. I deleted the app and re-downloaded it but when I went to my school’s schedule, the countdown started displaying multiple different countdowns while a red bar told me there wasn’t a schedule for the day. This hasn’t happened before and re-downloading the app doesn’t fix it. I’m just confused

I am a senior this year, and i have found this app to be very helpful in keeping track of timing and your schedule. All you have to do is enter in your school district and bam! 5 star for sure.

I love the app, I customized the schedule and I thought it would make a bell sound but it doesn’t Is that something I can fix, or is that not in the app yet
