The data only pulls 3 months of data from the time of first sync, it doesn't retain data from a whole year as it should most likely have. It doesn't allow you to see information on eBay details after 90 days aside from some simpler details like item name, price and a few others like product id.

Exported Data only shows the first purchase as April 5th, which was around 90 days from when i frist synced my account with Juiced. This is true for eBay, I believe you should have no API issues with Amazon or Shopify on pulling data over 3 months timeframe, but this needs to looked into for eBay. Especially for Exported Data
