So, while trying to make a quick search for PCID (cause the stock one is broke as a joke right now), we (@josecgomez ) noticed that there’s a new “Feature” in which they make this read only check box so you can’t make the field a drop down (by faking the updateable and then using the advanced editor configuration). We use this all the time. This is a very common thing that we do for making tracker selectors without having to write any code or do customizations. @timshuwy was this intended to stop this? This is been a thing we’ve been using for years! Anyone else having problems with this?
you were probably 'using" an undocumented “feature” that was “fixed”. have you tried creating a service call? if you report it, and state the reasoning, the dev team may be able to research to find why it was done or if it is intentional.
