As of Jan 26th, 2023, you may receive a notification from Shopify about the ‘unsupported apps’ and it may include Boost Product Filter & Search app. We have found that it was due to a single unexpected Shopify API call using an outdated version and had been completely resolved immediately. However that notification will be showing within 14 days by Shopify until Feb 9, 2023. Please ignore that notification and be assured that the app has been working correctly for all stores.
