I have a product attribute
full_short_description created from admin panel. For already existing products, I am unable to update the attribute value. But if I create a new product, I can change the value and it is showing the change on frontend too.
For existing products if I change the value it is showing product saved successfully but in admin and frontend showing the old value only. The value is not even updating in database.
Reindexing is done.
Setup upgrade and cache flush also done.
