Thank you for your response.
I had the same search issue on a laptop device, but I was able to see the station on the map and add it as a favorite. I found that if I deleted the app on my iPhone and iPad and then re-installed it, the issue was resolved. I still can’t search the station using the search feature (KKYGEORG62 still pops up, but not KKYGEORG112), but I could favorite the station by finding it in the map. I don’t dare click on the KKYGEORG62 station from the search, because I’m afraid that will mess things up again.
Thank you for your help! I think I’m good to go now.
