I keep running into a limit on Nawi after starting on my second practice round and I feel like the practices have been pretty short. I have to wait about 4 to 4 and a half hours before I can continue or start a new chat. The message says it's because there is an attachment, but I only copied and pasted the prompts from the lessons. Do I need to type out the prompts instead of copying them? Do I just need to start over for each practice round?
