this has just started happening in the past week, the Google search on my xoom won't work, it just gives a webpage can't be displayed page and the play store times out, if I do a soft reboot they work again for a short time, any ideas ?
You could try uninstalling Google play (restores to factory setting of app). I also had a problem with the Google play store this week on my galaxy tab (force closing). I uninstalled it and now it's working again.
