User Item Card Display Issues on Sales Order

This user can modify the Item Card for Model/Finish/Cover/Size extension fields but there seems to be a lag between when she types this info on the card and when she sees it . Then, there is second lag with transfer to Sales Order when Item is added to the line. Your thoughts?

Is this a SaaS implementation or OnPrem? I’ve also seen some delay in the SaaS version when updating fields so this may be a known issue.

What Version?

Is there any code associated with the extension fields or was it just adding the fields to the table?
