Take your time to conduct this job, and you will have a working iPad again
The digitizer broke. Luckily, the LCD is still working (and without a scratch!)
As I stated in the title, as long as you are patient and through when removing the broken glass, clean things out with some canned air, this is a simple job.
To ensure the digitizer attaches firmly to the case, I placed a weight on the digitizer for 24-hours. There's really no need to rush and get this job done immediately. Take your time, ensure you reconnected the LCD and digitizer ribbons and that they will not be an obstruction when you attach the digitizer to the case.
