Is anyone else having trouble with dashboards in Lightning? As someone who views and edits dashboards daily, I find the slow load times for refreshing/editing Lightning dashboards maddening, and I would say 10% of the time the changes that I've just made get reverted upon refresh (particularly when changing the number of decimals displayed). I also frequently get error messages saying my component can't load because something has changed in my source report when I am 100% sure that's not true. I am also extremely disappointed that Lightning tables cannot display custom formulas, unless using a legacy table which has severe limitations.

I love the look of Lightning dashboards, but it seems like every time they roll out new functionality, there are also new bugs and glitches and it's very frustrating!
