I upgraded, and a few fields in a base form can no longer be edited or even tabbed, but can in the table.
I don’t know how to fix. AI always seems to give advice from other Libreoffice programs, and Base is often different.
AI said " This typically happens because LO changed how form controls bind to fields, and older forms lose their “Data Field” binding.", but any advice on how to access and fix have been wrong so far.
