There’s no lock at all on the business you selected. In fact, you created it yourself, so there are no restrictions at all on you continuing to edit it further.
I’ve just changed the business name for you anyway, but you’ll have to upload photos yourself. You should be able to edit all details about this business in the Waze map editor.
Adding photos from the editor is not possible for L1 users. You could add more from the app, but in the meantime I’ve added this photo my end, hope this helps.
Strange, all fields appear disabled to me, as well as with the “forbidden” mouse cursor icon:
Either way, thank you both for changing it, I’ll mark it as solved.
