SafeSense review for Shopify Marketplace Connect

App was working great, then they changed something forcing it to now send Walmart orders to Shopify with sale tax. According to their knowledge base and all documentation, it should not do this, because Walmart collects and pays tax. So we are now stuck doing manual adjustments for tax on every order to ensure we don't double pay tax. The app has become unusable. Tier 1 chat support acknowledge the bug but then moved to email where the dev team was going to work on resolution. However, decided not to do anything about it. They won't say anything more than "This is how it works" and wont escalate or assist in any way. Support is simply ignoring the bug that they know exists. We're trying to find a 3rd party app that will work. This doesn't!
