In Portugal now. I submitted about 20 different locations, including many in Madeira.
I wouldn't be able to fly in all these locations but I wanted the option to fly in some of the locations, depending on weather and schedule.
I had only two rejections, one was the marina area of Funchal. I forget the exact reason they rejected but it wasn't a high-priority location for me.
The other rejection, at Sao Laurencio, the Pontas extending out into the ocean in the NE part of the island, was initially rejected because I chose the wrong jurisdiction. Actually if you look at the map, it's very close to the airport so some parts of the peninsula is definitely NFZ or need specific approvals from air traffic control
So I resubmitted that one with the correct jurisdiction and it was approved though they cut the range from the 1000 meters I requested for a Circular flight zone from the GPS coordinates I submitted to 500 meters. But they didn't reduce the max altitude of 120 meters.
I did the requests only in e-AAN portal. Presumably they contacted the IFCN on the island. They didn't tell me that I would need to do so on my own.
