Amp Back in Stock | Preorder

App has done beautifully for me but I have an issue with a Shopify update on my theme that now shows the customer the 'tag' "bis-hidden" for this app. App support can't fix it. And Shopify referred me to the app support as they can't fix it. So I am shopping for a new back in stock app. Keep an eye on your search boxes on the front end for this issue as it is confusing to customers.
