I have a multi-website Magento 2.1.0 CE installation, with 2 websites and different prices per-website. Prices are note related to each other, for the same product across the two websites.
In product listing pages (PLP), I keep seeing "as low as $55.55" for configurable prices, along with the correct prices, in non-default website 2, even though prices have been set correctly, all configurable children have the same prices $55.55 in website 1 (default) and $77.77 in website 2 (non-default). Configurable product itself has been priced accordingly, there are no special nor tier prices applied.
I've checked price attribute values in database, all prices are save correctly per-website. Checking the price index table, though, returns correct min_price and max_price for simple products but prices from the wrong website for the configurable products, which is causing the "as low as" issue in product listing pages.
No 3rd-party modules are affecting indexing (vanilla Magento).
Anyone had the same issue?
