Robert David Home review for Shopify Search & Discovery

The screen is blank. It does not work in any modern updated browser for me. Now it is impossible to edit Filters on any website. Have tried contacting Shopify but they keep saying I need to login to create a ticket. 1. I am logged in. 2. I contacted you via the app header from one of the stores I am using (the only bit that appears). 3. It has my email address in the ticket, so I must be logged in. Am I supposed to login somewhere else to contact you? EDIT: Also need to say, I never installed this app. It just appeared and broke the website for over 24 hours, with no confirmation from Shopify.
