How do I save the checklist?
So I bought a bin of used legos with 7 different sets. I separated them best I could and then went on to rebrickable and used the checklist to see if I have all the parts. Later I came back to find my list empty. How do you save your checklist? I have been trying to look up a video on YouTube and I'm not finding anything and just feeling stupid. Is it something obvious I'm missing here? I inventoried 3 full sets and have to start over because it didn't save which pieces that I have
