Hi HakunaMatata1928,
May I know if you have created a view (grouped by column)?
Based on my test, Edit in grid view appears if we are editing the list in normal view (All items) and if we are editing the list in Group by view, Edit in grid view is not visible. **** Please check if this is the case on your end.
Besides, please check if Quick property editingis disabled in the Advanced settings of the problem list. To confirm, open the problematic List> Settings> List settings> Advanced setting. If the below option is set to No, please switch to Yes and click OK to check the result.
Let me know the status. Have a nice day and stay safe😊
Regards,
Neha
