Dashboards are not refreshing

[googlogmob]

The problem is that dashboard tiles are not refreshing, whereas the report connected to the dashboard is updating properly according to the set schedule.
This problem became very frequent about a week ago, at the same time as the Shapes option was added. Since that only manual update helps (I simply repin the tiles to the dashboard). As I pin a fresh tile to the dashboard, the similar tile pinned earlier also gets updated.
But after manual repining of the tile, it is not getting updated anymore, unless I repin it again.
Please, advice how the dashboards could be updated regularly and automatically (without my participation).
