Sorry this must all come across as very confusing to you as you are new to the forum.
Repurposing of one previous wayspot into another is a topic that is not clear cut in some ways.
The basic principle is that the original wayspot was approved for that place and its function.
The case that is being referred to was a restaurant that changed owners but was still a restaurant. Hence my questions about previous and now.
In my opinion interpreting what you have said this is now very different from what was there and you are new owners.
It would be highly unusual for it to be changed via the property owner form. The more conventional and normally recommended route is to make a fresh submission.
It may be that the wayfarer team steps in as they did in another case.
In the meantime….
You do need a better photo without people in it and that you can see the title of the place clearly.
Try to fill the picture with the building and avoid too much forecourt.
@seaprincesshnb has made good suggestions for the text.
Good photos and text will be needed anyway.
