Bug in modifying the color scale code in iOS

[idefix37]

Since several weeks it is no longer possible to delete the code in color settings to replace it by a new one in iOS devices. Both in the mobile app and on the website.
This was possible previously to replace for instance the default code by a customized one. To do that it is necessary to delete the old code and then to copy the new one in this window.

Fortunately it is still possible to do it on desktop. But annoying for those who just use mobiles devices.
