I noticed that in POS Plus and Minus Buttons are missing. I tried a installing the ERPNext on a new server and found the same issue is repeating. Please find the screenshot attached. Kindly help if this is something that this happening to only me or there is a bug.
Yes - I can confirm the same on the demo (https://demo.erpnext.com/desk#pos). The buttons are there and clickable - they are just not visible.
EDIT: Created issue for this https://github.com/frappe/erpnext/issues/7420
Have fixed the issue and soon we’ll release the fix
