How to solve error 429?

I’m a student and was trying to send a form.
I use the android app by the way.
There were problems in submitting it.
I first had the error 403, but after numerous tries of resending it. I recieved the error 429.
I thought I should come back later as my teachers say it could be traffic but it has been 5 hours now. And it still says error 429. I’m wondering if there are solutions to this.
