If the user needs to add a selection to a dropdown list, they have a button that will open a "New" form. However in 5.8, the dropdown list does not automatically get updated with the new value. Seemed to have worked in the 4.7 version of the app. How do I do that?
if possible you could try and refresh the entity that contains the dropdown. This will refresh the options in the dropdown as it is being reloaded.
If this is not possible then you could try to use the lazy reference selector from the app store. This has a microflow attached to retrieve the values on click of the dropdown.
