I have noticed similar regression. Previous release worked fine but now the only way to have location available is to keep GPSInfo running all the time. GPS behaves like the initial position fix will not happen if long time has elapsed from previous fix. Maybe GPS firmware is not initialized properly. My device is Xperia XA2 single SIM.
Another problem in location is that sometimes Here can’t show whether to turn right or left because it doesn’t get location for a few seconds. Not good in a city you don’t know. Due to this I’m going to buy an Android phone to use when I really need to have GPS.
