My iPad screen randomly cracked, after putting it in a case.

I strongly suggest contacting/reaching out to Apple Product support and services on this issue.

Unfortunately there is no ‘shouldn’t have happened’ clause in the warranty. You can use one of your accidental damage instances or just live with it.

If it doesn’t bother you then you may want to wait a month or two until things calm down. If not since Apple stores are closed you’d need to use an authorized service provider for your repair (although what they will do is, if you pay the service fee, exchange your cracked ipad for another refurbished replacement)

We’re just users here like you, not Apple. I would imagine any exception or special circumstances would be at the discretion of the store manager when you take it in. So you could try to make an appointment and take it in and explain The situation and see what they do.
