I have similar sitauation but with labels. Query works fine if asigned value ist just one. If I asigne few values to to one custom filed, ACF returning me an array of values and i cant get to them. The query returning nothing. Any advices how to fix it?
`[meta_query] => Array
(
[relation] => AND
[0] => Array
(
[0] => Array
(
[key] => technika_wykonania
[value] => Array
(
[0] => ciecie-laserowe
)
[compare] => IN
)
)
)
)
