Hey,unfortunately we are still experiencing this issue on macOS Catalina 10.15.2 and Safari 13.0.4. It is behaving exactly as described by bburcea. Everything works fine until after some seemingly random amount of time either "SFSafariApplication.getAllWindows()" or "window.getAllTabs()" prints the "Error connecting back to host app" message.Is there anything we can do about it? Is this still a bug in Safari?Thanks in advance.
