I currently am exploring multilingual support for a multi-site installation, and as ever, relying on ACF for a lot of the configuration.
I will reply here with some outcomes but initial thoughts are:
* WPML seems to be the most advanced translation plugin – so support/solutions are widely available.
* Polylang – creates new posts for each language, so works really cleanly in that sense and with ACF – could be a quick option on that basis.
I shall endeavour to post back.
