Can't see items on POS when I add them to cart

I activated POS for Restaurant feature. Since then, I cannot see items i am adding to the cart. What am i not doing right?

Please help me

See screenshot below:

I am able to see the items in cart only after i click on order. Even so, the plus and minus buttons to increase the quantities are not responsive.

One of the issues can be that the product that you want to sell in the POS is not mark “For Sale” Check the product and set it for Sale

Click on order and they should appear, if it’s still not appearing then I don’t really know what’s the issue and maybe you should contact the support team.
