Sharing doesn't work on Autotrader app on my iPad

For the past 5-6 wks or so the share button on the top right corner of the screen in the Autotrader ipad app does not work. You can tap it all day, nothing happens. Have contacted Autotrader several times, they are useless. 9th gen iPad, iPadOS 18.5 (22F76). App version 4.17.0.

Has anyone else had this happen? Has anyone found a fix? Thank you.
