Import lesson didn't import all text
Yes, LingQ lesson can be maximum 2000 words long. If you are importing a text longer than that, it will be split in parts. In some cases it can take more time for additional parts to process and appear. Check the same course again now and you should see the complete text imported.
Thanks for your reply Zoran. That explains it. I didn't receive the rest of the article but I've reached my limit on the free account so that will be why.
