Facebook tile won't show new notifications

[sungibr]

Hi,

I've decided to take a shot with windows 10 on my Lumia 620. It's been two weeks now. Build is10586.164

So far, it's been reasonably stable and running not so slower than it was with win8.1. Battery runs as before, not the whole day, but maybe it's my battery, because it's been running this way for some time.

I have ocasionaly some freeze, and have to reset the phone to recover it. But it's rare now

But what bugs me it's the problem I have with notifications on the Tiles.

The Facebook won't show, or show old and not updated notifications.

Same goes for 6tag, whatsapp and email.

Any suggestions I could try?

Thanks!
