Gyv Me Body review for Shopify Collabs

My account was grandfathered into Collabs from Dovetale. I have spent 2 days trying to invite and receive an invitation to collab with another business owner. We both sent emails and messages and have not received any answers to what would be a simple solution. This app used to be so easy to use before it changed to collabs. I'm very disappointed. It has good features, but it's useless if you can't properly invite or register to use them.
