Hi Catherine,
Thank you so much for your support, really appreciate it, yes the problem is solved now. Suddenly another support ambassador intervened and was very professional. She solved the issue overnight. I really think Airbnb should quickly implement escalation routes and empower call center agents more. Also they shouldn't suspend anyone's listing without prior notification and clear rationale. Only mentioning this to you incase you have access to internal teams and can share the feedback.
Thanks a lot for your help again!
