calender sync

[Julia64]

Can Airbnb let me know why this function doesn't work anymore. Originally I was able to set the sinc through Airbnb on my iPhone app. It then disapeared.I have tried numerous ways but they don't work. On my iPhoneXR I've gone to "Link your Airbnb calenders" but there is no option to the iphone colender or any other just a link "Learn more" where the instructions  - but there isn't the option noted "Create linked calenders"

Very frustratiing as I use this calender for everything and it means I have to manualy enter the details.
