hi , aside from ranting here , if u read whole forum u will find the solutions of lagging issue.Just reporting what i find on the software that's all. If someone else has already reported the same issue i'm sure that's a good thing rather than bad because the issue gets more attention and perhaps gets fixed. The link's solution was to install older versions of google's apps ...somehow this doesn't feel like a solid fix to me. Perhaps i'll just suffer a version or two until things get fixed properly.
