Hi Riza,
Thanks for your patience here. You're right that there's a known bug affecting the GHL native calendar integration, and our engineering team is actively working on a fix. I'm sorry that's caused a gap in your bookings.
On n8n: that's a valid workaround but it does have a learning curve, especially if you haven't used automation tools before. If waiting for the native fix is an option for you, that's perfectly reasonable and you won't need to set anything new up. I'd recommend that path if you're not under immediate time pressure.
If you do need bookings working right now and can't wait, the simplest alternative without n8n would be using a [Make.com](
http://Make.com) scenario instead, which has a more beginner-friendly interface. That said, I'd rather not push you toward a workaround if the fix is coming soon.
Regards,
