I have not been able to find a post which relates to my problem, so forgive me if I have duplicated one.
Until recently, icons showing POIs have been visible on my maps which show the location of things like brand name petrol stations, shops, etc. These have disappeared. My map setting is set to Most Detail.
I have also noted that in various posts there are references to a Where to\Extras selection. In the 310 custom POIs are located in Where to\My Locations. Is that correct?
