We do not recommend attempting to download 10K contacts in a single export.
Please keep your exports to a maximum of 1K.
Sometimes a time out error can prevent LIX from exporting a large batch of contacts in one go.
If this error occurs, we suggest attempting a smaller number of exports per batch. For example, try to download 100 at a time, if this is successful you can then scroll along to the last page LIX was able to scrape and press the LIX-it button again to continue.
LinkedIn generally shows 10 users per page so you may have to scroll along to the 10th page to pick up where you left off, LIX should be able to start scraping again from there.
