Problem shopping cart

Hello all,
i am configuring e commerce on erpnext, i found a problem on shopping cart, when i entered shopping cart, if i changed the quantity by clicking the plus button or keying in. then the “request for quota” button no response no matter how many times you click it.

just reported this issue:

I have similar issue, upgraded to latest v14 doesn’t fix the issue. Place order button still stuck if we update the qty or even put remark for item. Need refresh page only able to proceed

ERPNext : v14.70.3
Frappe : v14.76.0
