I have that problem, too. And when the answer does appear I find that others have given the correct answer ahead of me. I see 'There are no answers at present' and by the time my answer arrives there certainly were 'answers at present.' l feel rather foolish as I wouldn't be giving the same answer over again. It happens quite frequently.
Mine can take over 30 mins to appear on screen. It comes up immediately through my profile ... strange !
Sometimes I can get all the help I asked for by the time I can see it on screen but it must be there for others to answer but I can't see it xx
