ACF: false if using V2 , but if I set V3 it the V2 URL works correctly returning fields

[amouratoglou]

Hi! I have updated Wp, ACF to REST and ACF to latest versions. I noticed this weird output of the API:

When I set V2 in the dashboard, some post types custom fields ACF returns from the REST API as false, but
if I change the setting in the dashboard to "V3", the v2 endpoints begins to work correctly returning the acf fields data in the json response...

the /v3/ URLs do not respond at all. is this expected, am I missing something?

thanks for so much!! cheers
