Here are the number of layers for each canvas size in Procreate
5790 x 5790px: 12 layers
6500 x 6500px: 8 layers
8000 x 8000px: 4 layers
A4 300DPI: 57 layers
A3 300DPI: 26 layers
What are you creating that you need 12000 x 12000 pixels? That's 8 times A3 size. Even a high specs computer may find it challenging to work on that, and iPad Pro 2017 only has 4GB RAM.
