Easy IO with Oxygen Builder
Oxygen Builder is one that we've seen a lot more in 2021, and unfortunately we've found some compatibility issues when using it alongside ACF.
Notably, there is a bug in Oxygen related to the "return value" option set for ACF image fields. Oxygen cannot handle a CDN URL when the "return value" in ACF is set to Image Array. The best fix is to change the return value in ACF to Image ID. This is the best option for performance because Oxygen uses horribly inefficient queries when either Image URL or Image Array are chosen for the return value.
If you find any other issues with our plugins and Oxygen, please let us know and we'll investigate further.
