IE Internet Explorer – Error

Hi.

It is not possible to complete an order on the checkout page, because the error message always comes up that you should select an access point. But it is selected and works in all other browsers.

This error only exists in IE (version 11) and Safari (smartphone).

In IE the console shows the following:

Warning: a promise was rejected with a non-error: [object String]
    (No stack trace)

Please fix.
