In the morning after I updated, I checked and I saw Thomson. I thought it was normal coz I stay at Bishan. Was using wifi at home then
But after I reached office at MacPherson, in office using wifi, it was still showing Thomson.
So I played around it, I allowed it to use 4G data, then let my phone to use 4G, and check Weather again. Then I saw there are now this little compass icon and a dot at the bottom. The compass will show my current location, Ubi, the little dot still shows Thomson. I don't know what is that dot for, maybe previous location.
