#2. Also the Top right corner box for the team position during live race is also a miss I understand this might be due to space constraint.
Could you provide a screenshot of what you mean?
#3. Yesterday attended the First live race on app, was wondering is there any feasibility of KERS'ing both cars simultaneously as we can do on desktop/ laptop sites by S & K.
It is something we can review in the future, but not on mobiles at this time. There is only so much GUI space available, and a landscape version would not be ideal (we looked into it) because the text for timing, the driver panels etc. would become so condensed that it would be unreadable.
#4. the chat conversation is in white color which merges with background so we can't read what discussion goin on during race
This was a silly error, but it is fixed in a coming update to the app stores. We are going to launch a big patch fixing many issues very soon.
