Over the last few days, I took the plunge to upgrade to Digital and bought a ARC Pro layout, and I having major issues don’t know if its compatibility with the tablet on bad downloads. The tablet is a Samsung A7 quite new and up to date on SW updates, its hit and miss whether it connects you can see the ARC in the menu of the tablet but getting it to connect is 50/50. When you do get the app to connect and you try to calibrate the cars the first car will not do a full lap with out stalling regardless of the speed when you try the second car nothing happens at all. Pace car: You can set the speed up and its perfect (only one car on the track for this process) when you start the race both cars become pace cars and nothing i do can gain control of the race car. Racing: Both cars on the grid race starts, cars drive off but only one car registers with fuel and tyre usage and number of laps the other just runs and never needs fuel or tyres and regardless of the race length it goes on for ever. So, you can see I am struggling at the present time. So, the app as been removed and reinstalled a few times and each time it’s removed I restart the tablet and once its reloaded I restart the tablet, its fully charged so power is ample to run it. Any body got any clues on my next move. Mike.
