Thanks for the answer. This option works, but if you replace the existing field value, for example “+79998006655” with the new “+78009995566”, then everything is stored correctly in the database, and the old version of “+79998006655” comes to the administrator’s email.
If the custom field is a checkbox, then it is correctly stored in the database, but only “Array” is shown in the administrator email.
How can this be remedied?
