4.3.1 is the worst version yet. We were at a Porsche track day last week and at least 4 of us failed to log a single session without the app crashing. This was across a combination of GT4's, GT4 RS and Spyder RS's.

Previous versions used to be fixable by reinstalling the app but now it simply doesn't work.

I have persisted with PTP for years due to the data being so complete but this is wearing really thin.
