However, when I upload the extension file, the changes made in Company 1 show up in Company 2 and Company 3.
Can anyone help me make the extension I made visible only in Company One and not in the other two companies? I am a newbie, so please guide me through this if possible.
(For Example, the extension I have created will create two new fields in the sales order page, which is necessary for company 1 but not needed for company 2 and company 3, so I don't want the two fields created using the extension for company 1 to show up in company 2 and company 3)
