@flyingant – as I said, we were able to use the plugin to import to repeater fields but it took a long time back and forth with the plugin’s devs. It took us over 3 weeks testing, recording screenshots, reporting and effectively beta testing their product for them!
The cost of those 3 weeks massively outweighed the cost of the plugin!
It has the distinction of being equally the best and worst premium plugin we have ever used.
I have urged Elliot to develop his own importation add-on specifically for ACF as I feel it would be in better hands, and could be lucrative for him too.
