Smart Suppl review for Preorderly • Preorder PreSale

[Update] I've recently left my review here that arose from the frustrations I've got from the app developer's email. However, I restarted using the app and it's working fine for certain products I need the app for. And I got multiple reach-outs from them since the incident. It's clear that they're taking responsibility for their work and provide support even I'm not a paying user. In the light of that, I am here to update my review to reflect the latest status (the old one has been deleted by me which is not relevant now).
