Anyone got any solution for this issue. Same thing is happening with us as well. We have created Multi field components on dev environment , On dev environment these multifield components is working fine. When deployed these components on AMS cloud these components are not working. As mentioned in this post , dialog is taking values from users but doesn't store in repository and resulting empty JSON to WCMUsePojo.java
We have also tried to installed ACS common 3.17.0 - 3.17.4 but no luck.
