Rosa Bloom review for Amp: Back in Stock & PreOrder+

Had great support when I first installed this app 6 years ago, however recent support experience has been disappointing. Support denied that their app was causing the issue I was experiencing, told me to contact Shopify support. Shopify support said it was highly likely the app was causing the issue, so went back to support who escalated it to Tier 2, whatever that means - still haven't heard anything two days later.
