The point of sale user interface has been adapted to work on mobile devices. We modified the design of payment lines to look like payment methods and stack them together in the mobile view. When you had a cash method, the amount was not preffilled during payment, now we always prefill the amount to keep it more simple. closes odoo/odoo#51891 Task-id: 1887609 Related: odoo/upgrade#1334 Signed-off-by: pimodoo <pimodoo@users.noreply.github.com>
