WordPress (Legacy)

I had a zap working with WordPress (Legacy) and this has stopped working – https://prnt.sc/qV6140lFr2t0

I have created a topic for the Zapier plugin but no support whatsoever – https://www.ads-software.com/support/topic/wordpress-legacy-has-been-deprecated/

What was in WordPress Legacy that had this simple zap working? I’ve tried disabling plugins (those that I can), changed permalinks settings in WordPress, updated WordPress to the latest version and error is still there.

Any input will be appreciated – I need to get zap working again and Zapier support is hopeless unless I get to the paid plan which locks me in for a year.

Thanks.
