My name is Anne, on the Guru team. Thanks so much for getting in touch with us!
- Can you let me know what you are finding isn't working for you with the POS app and we can look into it together? Hopefully we'll be able to work out a solution for you, and make a feature request if there is something you'd like to see that isn't available right now!
I just wanted to let you know that it is possible to review the POS app on the app store also, you can find it in at the bottom of the page- https://apps.shopify.com/shopify-pos
Thanks so much!
