Klaviyo not receiving data

Same here. It looks it i not working at all. It is irresponsible not to answer for so long on support request.

I have the same problem here.

Is it possible to have support please ?

You can try Advanced Form Integration by nasirahmed until this plugin is being fixed. It worked for me.

Thanks for the info @valekavale but I finally discuss with chat support and it seems that they will need to fix the free version since the paid version work fine.
