Hey there! It is really new, so would love to hear any feedback! I know in the Los Angeles Space Slack Community there are a few people chatting about it as well. Looking forward to hearing more from the community here.
Shopify Balance is fairly new still but we have seen a lot of merchants opting in and really enjoying their experience with it.
In order for you to get a better reach with your question so you can hear from other merchants about this, I would recommend reaching out in our general discussion board instead of just the regional board for Los Angeles: Shopify Discussions - Shopify Community .
If you have any specific questions about Balance please let me know and I'll be happy to answer them for you.
