Any chance to have a Google Calendar two-way availability sync? For booking coaching sessions etc.
Is this on the roadmap? Any solution to use a similar solution now with ShareTribe?
Thanks 
Right now, there isn’t such a feature in Sharetribe Go, indeed. I don’t think will add it anytime soon.
I’m not sure if anyone has build such a synchronization with the Community Edition of Sharetribe Go, but this is of course something you could consider.
However, it is something that would be relatively easy to customize with Sharetribe Flex, as it already has all the components/features/APIs to do this. If this is a key feature for your marketplace, I think Sharetribe Flex should be your next stop!
Give it a try, and don’t hesitate to reach out to our team from your Flex Console, we’ll be happy to help or connect you with a Flex Experts who can build this customization for you.
Hopefully, this helps
