WiFi Auto Connect not working properly

I have my home WiFi saved on my OP3. When I go out of the range of it, it gets disconnected (obviously) but when I come back to the range, it does not connect automatically even if the WiFi is ON.
I have not changed any WiFi settings except disabling the WiFi/Bluetooth scan for Location.
Any ideas?

I am on unrooted stock OOS 3.1.2, if that info helps.
