These locations auto-populate when I begin writing them in the search which makes me believe they are available to add as service areas but this happens after I press apply. Very strange.
I have tried adding London as well and the edit won't stick.
I am having an issue when adding new service areas. I added 6 new service areas and 4 of them were rejected instantly.
When attempting to override the rejections, I was met with this:
All of the service areas added previously were accepted and not marked as invalid before.
