For my experience, if u go online, and running on another apps(e.g waze..etc), b4 accepting any a trip request, u wil see the prompt out notification in every few min, to confirm u wan to sty online or offline, is very annoying, but sometimes didn't prompt out, if u did not response within a sec, it will logged off, unless u keep remain on the uber partner apps screen.

if not misstaken, the KLIA zone their set for FIFO - the request will fall into who waiting the longest by queue. ... not ez fast getting the request..

So lucky.. I dropped 1.. then waited almost 1hrs+ empty car back ...

below link for Penang Airport FIFO even JB Airport also same, not sure for KLIA/KLIA2
