Prestashop: Mobile phone field for customers can't display

[LouiseBonnard]

Describe the bug
I want the mobile phone field required for customers who registered. It does not appear in the front office, even if it seems okay from the back office.

To Reproduce
Steps to reproduce the behavior:

1. Go to the BO, in Customers > Addresses, select the _phone_mobile_ field to make it required.
2. In the FO, log in or sign up, go to the Address section to add one or complete one.
3. Error is: everything works fine for the _phone_ field but nothing changes for the _phone_mobile_ field. It does not appear at all.

Hi @LouiseBonnard,

I think this is not a bug, this is a configuration issue.
We need to navigate to BO => International => Locations => Countries => Edit the contry selected => add the phone_mobile to the address format.
@marionf, @colinegin what do you think?
Thanks!

Yes @khouloudbelguith that's it :)

Dear @khouloudbelguith, @marionf, thanks for your comment. You're right, it works if you edit the country in the International > Locations > Countries section of the BO. And that is pretty tricky if you're not aware of it. Could it be optimized in some way, @colinegin? At least, in the short term, perhaps we could improve the information static alert in the Addresses pages of the BO by adding wording? We could indicate: _Select the fields you would like to be required for this section and check the address format (here, insert a tag for a link?) to see your modifications taken into account._
