I actually got this aia file from youtube but I can't make it work. I am using an esp32 and a gps module to collect gps data. the data collected is successfully stored in firebase rtdb but I cant seem to display those data on a map in MIT app inventor. I tried the show user property and it works thanks it's a nice feature. Can you help me with this one?
