Problem:
The client is using ACFML version 2.1.4.2 and has encountered an issue that hasn't been addressed in this version yet. They mentioned that a known workaround still functions.
Solution:
We have acknowledged the issue and confirmed that it will be addressed in future releases of ACFML. Meanwhile, we recommend continuing to use the existing workaround. Please ensure to back up your database before implementing any changes.
