same here, it's been like that for about a month. I had it, now it's blank. I just had an app update on iPhone hoping it'd fix this, but it didn't. I wonder if this will effect my Tesla score and insurance payment.
got the update yesterday, mines the same as yours. no graphic. hope they are able to push a update soon to get the graphic back, I use that all the time.. 2013 p85 w/MCU2.
